Can you arrange to post an image of the graph you mentioned above?Originally posted by magnet@Jun 11 2005, 03:24 AM
I would like to calculate the the frequency of a carrier signal from a graph of amplitude-modulated waveform. Can anyone supply the equation please.
Thanks

The time base of the oscilloscope is set to 100us per division and the verticle axis to 1 v per divisionOriginally posted by Brandon@Jun 11 2005, 05:52 PM
Very easy to answer. Formula is
1/(time between 2 peaks)
Since it AM mod, it easy to see. Just look for the AM mod. You will see high peaks and low peaks, one after another, this is the AM mod. The contour of the peaks is the actual signal carried by the AM mod.
