Thank you all so much. I am able to get the single peak with the sin wave. I go through the readings when time allows, thank you for the suggestions. In the mean time, I am curious to know if GRC is able to produce a FFT for a wide band. For example, can it produce one for the FM radio channels, show its various peaks.
