hello, please help me out.
i want to use pxi 4472 card read dyanmic signal coming from vibration transducer.
i need to display 20 frequencies (less than 500Hz) that have high magnitude than other frequencies with resolution of (df)0.5Hz.
i used measure spectrum express vi to get the amplitude at difference frequencies,
but problem is execution time is around 2sec for resolution of 0.5Hz
my observation is resolution df= 1 / (no. of sample / sample rate) = sample rate/ no. of samples;
means at 0.5hz resolutions taking 2 sec
after execution of the program what ever output data not accurate.
suggest me.
