How can I measure the hertz in a wave form?

How can I measure the hertz in a wave form?

As an example, this is from BBC Technical Requirements for HD material:
3.1.1 Stereo line-up tones
All stereo tracks must use EBU 1KHz tone (left ident). All tones must be sinusoidal, free of distortion and phase coherent between channels.
Digital Audio Reference level is defined as 18dB below the maximum coding value (-18dBFS) as per EBU recommended practice R68.
See also:
http://www.bbc.co.uk/guidelines/dq/pdf/tv/tv_delivery_to_network_programmes_v1.2-2011.pdf
for full document.
And for BBC Radio:
Not every Network requires tone. Check the delivery requirements with the commissioning network or click here.
Reference tone, where used, should be at -18dBFS or PPM 4 on A, B and/or M.
If submitting material with reference tone, tone and programme material must be have been monitored and measured through the same technical chain. The level of the tone must be equivalent to 0dBu and no less than 8dB below peak audio level for the programme material.
THE LEVEL OF TONE MUST HAVE A KNOWN RELATIONSHIP WITH THE LEVEL OF THE PROGRAMME MATERIAL AND THIS MUST BE STATED; for example: “Tone at 8dB below peak programme level”.
As a newcomer to digital sound (my background is camera) I confess to being somewhat confused. We are normally told to record at the highest level possible. So for voice podcasts I tend to record at about -6dB below peak for maximum volume, distributeds on MP3 files.
But I can underatand that televison and radio especially for analogue transmission) may have limited headroom, hence the requirement for -18dB peak = 0dBM.
I remember when we first rented out Digital Betacam cameras, some recordists were recording almost everything OVER -18dBM.
I suspect that until we have an all-digital world, these requiremnents will still be in place.
Many thanks to all. It's a ghreat community!

How can I measure the Graphics Card usage? I.e. percent load

Hello,
How can I measure the Graphics Card usage, like with the processor in Task Manager, but instead giving a percentage usage for the graphics card instead? Is there an easy way to do this, or would it require a lot of code? Is it even possible?

Ah, so It's unlikely that Java3D will include anything for reading this data then? I was really aiming at measuring the GPU usage under this API which although i have limited knowledge using, I do at least have some knowledge - I wouldn't have a clue how to access any other API's!
I'm using an NVidia TNT2 card at the moment, which is quite old.

How can I measure the thickness of a circle line?

Hi,
we try to measure the thickness of a circle line to find out if the circle is round or if there is any deviation in the circle. By now we are using the FindEdges tool and measure the circle at different points.but this is not sufficient.
Does anyone has an idea how we can measure the thickness of the line of a circle?
thanks

How can i measure the speed of the fan in sound and vibration signal simulator box

how can i measure the speed of the fan in sound and vibration signal simulator box
provided the values tach out:2 pulses/revolution and maximum speed = 6000rpm

Hi. I tried your suggestion and I could not get it to work well. In
fact it worked better without the running average (which suprised me).
I also played with the number of data points but still could not get it
to work well.
Do you have any other suggestions on how I could sort this problem out?
I
have attached a screen shot of the signal. To recap, I'm trying to
measure the'y' position of the flat regions of the signal. The signal
does not have a constant level, so this 'y' position varies with time
in a non-unform manner.
I am currently differentiating
the signal and selecting the y position when the differential is equal
to zero (within a tolerance band).
In the screenshot, the
signal has been zeroed using the method I have described above.
However, it occasionally has glitches which may be caused when the code
picks up a zero gradient at a peak or valley in the signal.
I therefore need some kind of algorithm that only measures the position of the flat regions.
Many thanks
John

How Can I Measure the CPU Power My Flash Movie Uses?

Hi All,
I'm working on a complex job that is intended to play on low-end PCs so I'm looking at ways to reduce the processor load the movie needs to play. Obviously large screen size, high frame rate, intensive ActionScript, and complex graphics all add greatly to how much CPU power is needed to run a Flash movie, but is there a way of getting an accurate reading of the CPU power it is using? I am modifying a job that was running badly on low-spec PCs so now want to adjust it to run faster and smoother so would like to somehow be able to compare the modified job with the original. Any Idea how I could do this?
Any help would be greatly appreciated.

How do I measure the CPU/GPU split of load/usage in Java3D?

Hello,
Is it possible to measure the split between graphics and CPU usage to find out how much work each is doing, what work is done, and which is doing the most work, for example? If so, how can this be implemented in the Java3D code?
For example, on a particular system, measure whether the GPU is doing the most work, or the CPU.
Thanks for your help :)

In Linux, you can read /proc/uptime. It does NOT give you the load averages that the command uptime gives. It gives you numerically the amount of time the CPU was idle vs how much time it was spent doing something. You need to read these two floating point numbers one every second, or once every 5 or 10 seconds then do the delta on the change: The maths are as follows:
Read the file in twice in 5 seconds, parse into two floats/doubles:
double[] last; // the first read of the file
double[] rect; // the latest read of the file
double ld = last[1] - last[0];
double rd = rect[1] - rect[0];
double cpu = (1.0d-(rd/ld)) * 100.0d;This should print the CPU percentage in Linux for that given time frame (5 second updates).

How do I measure the period of one TTL signal and the delay until a second TTL signal?

Hi,
I have a PCI 6024E board, the SCB-68 terminal box and am running LabView 6.1. If needed I could install 7.1.
I have two Honeywell sensors (HOA7720) which each consist of an infrared transmitter and a infrared reciever. When the beam is broken they output 5V, when the beam is open it outputs 0V. These are sensing the presence of a hole in two discs passing thru the sensors.
So as disc 1 rotates the signal is 5V until the hole passes thru sensor 1, then it drops to 0V until the hole passes. Then it jumps back to 5 V.
Disc 2 is rotating at exactly the same RPM as disc 1 because they are coupled with a spring loaded coupling. There is a delay between the first hole passing thru sensor 1 and the second hole passing thru sensor 2. The delay increases with torque.
Using the oscilliscope function and connecting Signal1 and Signal2 to AIn0 and AIn1, I have verified that the TTL signals are there. So electrically everything is working. I just need to know how to measure the period and delay. I'm familiar with A/D, but not with counters/gates etc and I think that's what is required here.
The first measurement needed is RPM.   Somehow I need to measure the period of the TTL signal.
The second measurement needed is the delay between the 1st falling edge and the 2nd falling edge.
I don't think it's possible to use the millisecond timer for anything, because the accuracy wouldn't be good enough. At 3600RPM the disc will spin 60 revs per second, or one every 17ms.  A resolution of 17 samples per revolution is not good enough.
Help please!

It worked!
I ended up figuring it out today. It's really simple. I went analog in to AIn14 and AIn15 which were free. Then the program does a multichannel scan of the signals (collects array of 2 waveforms), Signal 1 and Signal 2 at some scan rate. I used 100,000 S/s for 10,000 samples. Then I split the array into two separate waveforms. Then I did an edge detect on each one and it returns the position in the array where the falling edge occurs. The difference is the delay (after correcting for the scan rate), unless Sig2 comes first in which case the delay is the period - (or +) the difference
To find the period I used a subset of the Signal 1 waveform from the first falling edge on to the end of the waveform, then did the same edge detect except set the reset setting to true instead of false so it wouldn't detect the low signal which was now at the position 0 in the waveform. So it would ignore the initial low value, wait for it to go high, then detect the falling edge position.
Anyway, it works awesome, seems very accurate and gives very stable readings. 3600rpm no problem. It detects changes of one or two degrees in angular position, with a range from ~145 degrees to ~280 degrees

How do i measure the frequency of a sine wave using a field point counter module

I need to measure the frequency of the sine wave using field point. is it possible and if yes how. do i need to convert the sine wave signal to square wave. Please let me know.

It probably would be easiest to convert the sine wave to a square wave with a simple external circuit and then use a counter module to measure the frequency. There is a shipping example in LabVIEW that shows how to measure frequency with a FieldPoint Counter module.

How could I measure the excution time of the VI

hiii
I need to measure the execution time or the elapsed time of the prog in LabVIEW , I know that this time is very small but I need to calculate how much it is?
are there a suitable vi to do this in lib of LabVIEW or we must build it?

There is an integrated tool, the VI profiler, Darren presents it here.
You can also find usefull info if you go on the LabVIEW community and search for "VI profiler" or "performance", you'll find all sorts of articles, blogs that can help you : https://decibel.ni.com/content/search.jspa?peopleEnabled=true&userID=&containerType=&container=&spot...

How can I measure the full width half max pulse-width of a gaussian function?

Hi I am measuring a laser pulse using a Tektronix scope and feeding that data into my labview (v 7.1) based data system on a Mac OS X computer. I want to measure the full width pulse at half the maximum peak. The included measurement VIs that come with labview and the tek scope dont seem to do the job (even though the scope itself can do the measurement). I've attached my example VI. If anyone has any suggestions that would be great.
Thanks,
Paul

If you can display a trace on the screen, you can get the full width at half maximum. LabVIEW gives you several options:
Use the Pulse Parameters VI to determine the width directly. This will be a width based solely on the data with no assumption as to an underlying model.
Use the Levenberg Marquardt VI to fit a gaussian to your curve, then calculate the full width at half maximum from the coefficients. Levenberg Marquardt is a least-squares/gaussian algorithm, so is somewhat noise sensitive.
Use one of the minimizer functions (e.g. Downhill Simplex) to construct your own fit using a different assumed error distribution. If you are unsure how to do this, check out a copy of Numerical Recipes in C by Press et. al. and read the section on data fitting.
Do your own data based calculation. Find the peak with Peak Detector. This will give you the magnitude, but you may want to verify it with a polynomial fit (parabola is usually good enough) across the top of the peak to avoid noise problems. Then find the positions of the half-maxima on either side of the peak. The Interpolate 1D Array will probably prove useful for this.
Choose your method depending on your pain threshold and how accurate and robust you need the result to be. Good luck!

How can i measure the time between two successive rising edges ,using digital input ..

Hello
I'm trying to measure the time in seconds between each two successive rising edges on a digital input .
Till now I have managed to detect the rising edge ,increment a counter with each rising edge ,and snap the time at which the rising edge happenned
all I need now is to subtract the current rising edge time from the previous rising edge time in order to calculate (T) which can be 1/frequency and display it in realtime to the user.
but I don't know how to do this
Can somebody please help me !!!
note: the time that I'm measuring ranges between 200 ms - 2 seconds
Solved!

Counter without time.vi ‏11 KB

Cheers for that. It's always a good idea to post your SubVIs as well - the problem could be in one of those.
To help you out:
You already know how to use shift registers so why not use one again for time? Create a new shift register for the time then simply compare the "rising edge time" to the the previous time stored in the shift register and then write the new time to the shift register.
Just a few other pointers:
1. You'll want to initialise your shift registers ie wire a constant to the left hand register outside of the loop. This will cause the register to be reset each time the program is run. This is so that your counter will start from zero each time you run your code.
2. You don't need to use the "greater than?" compare function with boolean as they can only be true or false (1 or 0)! The "Equal?" function is what you should use here.
3. Lastly, it's a small thing but you can use the same tunnel that feeds into a case structure in each of the cases - no need to create two tunnels for the true and false cases, use the same one.
