Hi Isaac - it sounds like there's a beat frequency - probably between
the pulsed signal and the second freqency. I'm assuming you didn't see
the problem in the pulsed signal signals.

The definition of the beat freuency is the absolute difference between
two frequencie.

Hello everyone
My name is Isaac. I'm dealing with a curious behaviour that I can't
understand...
I'm generating my pulsed signal by multiplying a vector source and a
signal source. Then I'm multiplying this pulsed signal with a
continuous signal source at the same frequency, passing then for a low
pass filter and seeing it in a time sink block.
The result should be a set of rectangles with the same amplitude and
period. The curious thing here is that the amplitude varies in time
(from 0 to max amplitude and vice versa). Any idea why the amplitude
varies in time?
I attach the flowgraph just in case.
Any idea or help will be appreciated.
Thanks
