Hello All;
Well now that I got the audio source working I have another problem. The sample rate of the audio source is set to 96K (so that I can sample a 40KHz signal). I have a frequency counter connected across my source, so I know what the actual frequency is. When I add or change the decimation in either a band-pass filter or FIR filter block it affects the Frequency scale of the FFT block. I found that I needed decimation in order to make the flow graph work properly. Is there some parameter I can change in the FFT block to compensate for the effect of the decimation ?? Or is there some other method of introducing decimation between the source and the FFT block ?? Thanks Again . Bill
