Estimate AC/DC of a sine signal

Hi,
i capture an analog signal (a sine) with labview and i want to extract several informations from the signal like : Amplitude, offset, peak value, frequency, etc.
I almost get what i want, but i can't get the correct value of AC / DC components of my signal.
For example, i receive a signal like this one :
y = 1.25 + 1.25 * sin (2*Pi*3000*t).
I except the following value :
f = 3000 Hz (I got it)
Peak = 2.5 (I got it)
Ampl = 2.5 (I got It)
DC = 1.25 (I got it)
AC = 1.25 and there is the problem. I don't have this value.
Maybe i forgot a vi in my design, or maybe labview can't process this value or maybe i'm do it wrong because i don't exactly talk about AC value.

Look at the terms you reported and compare to your equation. There is a "DC=1.25" and an "Ampl=2.5" in your list. Your equation describes a sine wave with an amplitude of 2.5 units (peak-to-peak) centered at 1.25 units. I believe you are trying to solve for an extra term!

FRF Problem about amplitudes of two sine signals

Hi everyone,
I'm carrying out a FRF operation between two acquised signals, so I decided to simulate it simply first.I created two dummy sine signals with 50 Hz frequency value and "1" amplitude level for both.And I divide the second signal with a integer and took the FRF function between them, as below.
as expected for all frequencies, the result is 0,5 which comes from the ratio of sig2 to sig1.
But, when I changed the integer value to a float, 1,3 for example, it results nonsense;
Why these two processes do not match?
Thanks,
Ozgur

Deborah, it happens every time as Jeff indicated. Thanks anyway.
Jeff, am I understanding right, you're saying that the graph shows the sum of the errors that caused by the uncertainity? And there is another thing, when the data is not simulated but acquised, there will be not a precise amplitude and frequency valuei will it the FRF block go crazy then ?
I've tried that process with several post-processing softwares; MATLAB, dbFA Suite (A vibratory daq system interface). All results different
Do you have any suggestions to solve that? Or can it be corrected?
Regards,
Ozgur

Sine signal with alternating frequencies.

Hello,
I am interested in generating a sine signal whose frequency and amplitude change after every cycle. For example: lets assume we have two amplitudes a1, a2 and frequencies f1 and f2.
I want a sine signal with a1, f1 and a2, f2 alternatingly. One sine pulse a1,f1 and other sine pulse a2,f2 and this pattern repeats.

Hello srikrishnaNF,
Thanks for the solution. But the issue is I just want to append one cycle of a1,f1 and one cycle of a2, f2. f1 and f2 could be DBL. Let me know if you have a solution. I shall appreciate it.
I would make an array for your amplitudes and frequencies. Use a FOR loop to create the waveforms and concatinate.

Need to generate a continuous sine signal to sound card output with volume control

I need to create a vi to generate a sine wave signal to sound card with Labview 8.5.
there is an example written with lvsound2.llb for it. but the volume control sucks. it has only 0~100 integer control and is not accurate enough for my application.
some one mentioned Contineous Sound Output.vi in Example search. But I could not find it any more in Labview 8.5.
Anyone could help? Appreciate it.

Could you please explain in greater detail what you mean by "the volume control sucks"? The volume control is a Double Precision Float data type not an Integer. By accuracy, do you mean that you are trying to get greater precision? If you mean that the example simply is not loud enough at the maximum volume, you can increase the amplitude of the sine wave. I hope that helps!

Mysterious sine signal

hello ni world
    i'm doing a simple measurement of speed with PCI 6251 and SCB-68.
                                                                    8
                                    sensor 1         ---|          |---
                                    sensor 2         ---|          |---
an object " 8 " will fall and pass the two sensors.
the sensors functions as follows:
in "normal state" it will send out 5V but
when the object is in between the emmitor and the reciever of the sensor, the liason will be cut and the voltage will drop to zero.
i have problems with the cabling scheme. because in the "normal state" i should have a horizontal line , indicating 5V, and when the object pass , the line will drop to zero line. something like:
                                |
                                |
                                |
but instead, in "normal state " , i have got a periodical wave that looks almost like a sine function, with a periode of 22ms and a large range.
where does it come from and how do i eliminate it ?
i guess the signal source is a ground referenced source because it has only one out-put voltage, one ground and one power supply.
so i choose RSE in MAX.
i am very confused about how to wire the several grounds. and about the power supply i dont even know where the groud for it is.
i have studied the link in Wang's post
it help to clarify some concept but in practical situations i'm still confused
thanks in advance

You have a TTL-compatible logic signal. To measure the time it takes for the object to fall between the sensors you should be using one of the counters on your DAQ device in two-edge separation mode. I don't use Labview, so I don't know what vi to tell you to use. In the DAQmx C API, you would use DAQmxCreateCITwoEdgeSepChan to set up a channel to do the measurement.
You may need to use a pull-up resistor to make the logic signal reliable. I think the device manual may have some description of how to connect such a resistor if you need it.

Prob in freqency of the acquired signal

Hi frnz,
I have a prob in acquiring a signal. By using DAQ iam generating a sine signal and iam acquring the same. During the runtime
i need to change the frequency. The Prob here is delay in changing the frequency. If the output sampling rate is 1000 then there
comes a delay in varying the frequency. If the o/p rate is 20k then immediate change in frequency occurs, but the frequency
acquired here is a multiple of 20 depending on the O/P rate.
Eg:      generated frequency=10Hz
                                   O/P RATE : 1000 ==>acquired frequency = 10Hz
   O/P RATE : 10000 ==>acquired frequency= 100Hz
                                   O/P RATE : 20000 ==>acquired frequency= 200Hz
Please help me out with this prob...........

you need to increment the "accumulator increment" during the duration of the chirp. the "accumulator increment" controls the frequency of the DDS cycle. by increasing it's value, you are increasing the frequency. the math for increment values follows the same math as determining the frequency to increment value.

Acquiring multiple voltage and current sine waveforms, and log them along with the respective time stamp in a file."

"I am doing a data acquisition project using a 16 channel N.I. series 6020E card where I want to capture respective current and voltage sinusoidal signals. I am planning on capturing four pairs of matching current and voltage signals. I planned on taking one reading across the channels every fifteen minutes. This reading will need to be 60 data points per period or 3600 readings per second per channel in order for me to recreate the sine signal to determine the phase angle difference between the voltage and current. I was able to get one channel to capture a signal but could not get more than one working at a time. I am also trying to sycronize the data collection so all samples are with respect to each other.

"Hi Cappy,
Could you post this question to the Hardware > Counter/Timer or Hardware > Multifunction I/O forums? I think you will get more responses there. Here is a link.
The hardware is usually a better differentiation since software can support such a huge range of functionality.
The data rates you are talking about sound reasonable. Are you using the USB or the AT interface?
One other thing to be aware of is that the samples taken will not be simultaneous due to the multiplexed nature of the MIO board measurements. However if you know the channel clock rate(output from one of the VI's), then you can calculate the time difference between each measurement and correct your phase measurements by that amount.
If you have more questions, please post this to the other forum and copy all of our discussion to let everyone know what we have talked about already.

I am using the USB connection. If anyone can help with or has a similar VI for this, it owuld be appreciated so I can work on the larger aspect of the total project.

The easiest VI to use for this acquisition is AI Acquire Waveforms in the data acquisition palette in LabVIEW. This VI allows you to perform a finite acquisition from multiple channels on your DAQ board. As John mentioned the acquisition from individual channels will not be truly simultaneous. There will be a slight time shift from one channel to the next on the order of the maximum acquisition speed of the card, 100kHz or 10 microseconds in your case. By accounting for this 10 microsecond delay between consecutive channels you can properly calculate the phase shift between voltage and current.

Suggestions to improve the filter output of the acquired pulse signal

Hello,
I am working with acquiring the pulse signals form DAQ using a sample rate of 1k and number of samples as 1k for every 1sec signal using the DAQ.
I am using the smoothing type filter with Moving average->Rectangular->Halfwidth=3 and passing the smoothed signal to the butterworth filter with my requirements of 2.3hz and 0.7 with sample rate of 1000.
Problem:The filtered signal is always starting form 0 instead to start with the first value in the acquired pulse signal.For example, starting from 0 instead to start from around 0.057 as shown in the images.
How to make the filtered signal to start from the original pulse signal value.
Thanks in Advance.

All filters have a transient response. A bandpass filter with a DC component at the input will have that transient strongly excited.
Some of the filter VIs have an Init? input. If the signal is continuous but is being filtered in segments, that input can help by retaining the previous state of the filter. The first transient will still be there, but later ones should be erduced or eliminated.
In the example VI attached you will find that there is a transient at the beginning of each segment. This is due to the sine signal not having an integer number of cycles.
The IIR Cascade Filter with I.C.vi and IIR Filter with I.C.vi in the Signal Processing >> Filters >> Advanced IIR Filtering palette have an initial state input.That might be helpful but calculating an appropriate set of initial conditions from the signal data may not be straightforward.
What do you want the output to look like? What are you doing with the filtered data? Perhaps there is a better approach than a filter.

Generate sine waveform (myRio)

What is the best way to generate a 1khz sine signal on one of the analog outputs of the myRio device? I tried a timed loop and the Point by Point Sine Generation VI similar to the Electret Microphone demo or this post: http://forums.ni.com/t5/Academic-Hardware-Products-ELVIS/frequency-matching-problem-with-myrio/m-p/2... by Sammy_K. But the resolution is a problem. The frequency is not very accurate and with a dt of 100 uS and a 1Mhz Clock I only get 10 samples per period. A dt of 10 is too much load for the processor (the deivce does not respond anymore and needs to be restarted). Is there a better way of generating a 1khz sine output or do I need to do this within the FPGA somehow?
Solved!
Go to Solution.

Hey JulianR,
The thing to keep in mind is that each time you call the Analog Write express VI you write one data point to the analog output on the myRIO. The rate at which data is output is determined by the rate at which you loop runs. You can use a timed loop in LabVIEW to write analog output values at a relativly fixed loop rate and vary the value to generate a sine wave output.
I put together an example of doing just this (but using the value to set a PWM duty cycle rather than analog output) in this thread. You'd basically need to replace the PWM express VI with the Analog Output Express VI.
Finally as Marc67 mentioned you could implement the sine wave output in LabVIEW FPGA which would give you more control and let you use faster output frequencies. I'd start with the timed loop method and move to FPGA if you need faster output rates.
Let us know if you have more questions for us.

How to synchronize the signal sending and data acquiring process dynamically with one DAQ_Urgent

Dear Sir,
I am using one DAQ card to send a modulation signal (which is a signal summed by a low frequency saw tooth and high frequency sin signal) to the laser controller, and acquire voltage signal from another instrument (It is in a same measurement system with the laser controller)?
I would like these two process happening at the same time.
In the attachment, there are two parts, one of them is signal generating program, the other one is data acquiring program, how to do like this: when I press"run", first the modulation will be sent to the laser controller immediately, and at the same time, the acquiring program starts as well...
In addition, I think my program is not complete, could you please help me check if there are any other problems with it?
Thank you very much.. and appreciate your quick reply in advance.

Hi Memorysun,
Thank you for your post and welcome to the forums.
From your description what you want to achieve is:
Write data to a Analog Output channel that is then recieved by the Laser
Acquire (read) data from using an Analog Input channel (output from Laser/Instrument)
This can be achieved using a single VI with 2 seperate DAQ tasks, one the "Continuously Writes" to the Laser and the other that "Continuously Reads" from the Laser/Instrument. Can I recommend the following examples that can be found in the NI Example Finder (Help>>Find Examples>>Hardware Input and Output>>DAQmx):
"Cont Gen Voltage Wfm-Int Clk.vi" (for continuous writing)
"Cont Acq&Graph Voltage-Int Clk.vi" (for continuous acquisition)
The code from within both these VI's can be placed in a single VI therefore achieving the desired functionality.
Many Thanks
Jamie,
They would be better served with an example that routes the AO hardware sample clock to the source of an externally clocked AI.
Using the examples you posted will still leave them with the challenge of trying to alligh stimulus with response.

Labview, Change the phase between 2 signals dynamically

Hello,
I'm working on a big VI , and for testing my VI I have some controls. A part of my VI is to generate 2 sine signals with the same amplitude and frequency and a phase difference between thoses 2 signals.
My example is quite simple but very similar the one I use :
- I can change frequency and amplitude while the VI is running.
- I can't change the phase.
Anyone have an idea ?
