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 Isaac t.
