Hi there,
I have been dabbling with a ring modulator using the two transformer and 4 diodes forming a ring method. I think the important thing here is that it's output produces the sum and the difference of the two frequecies applied to the input. If I use a 1KHz signal for the carrier and 100Hz signal for the modulation and then view the output with an oscilloscope, I see that the modulation frequency appears to have doubled ie the periodic time of the waveform has halfed. Is what I am seeing the result of the sum and the difference of the two frequencies ie 900Hz and 1100 which equals 200Hz?
any views on this would be gratefully appreciated.
best wishes,
Lorraine
