rochelle-salt piezo divider

preserving modulation while dividing carrier - bottom trace is drive, top trace is output.

 

This is a montage of two photographs of the spectrum analyser output. At the central peak in the lower trace the frequency is twice that of the central peak in the upper trace. Amplitude modulation is present on the drive, lower trace, and is preserved after the carrier is divided by 2. This is a useful way of dividing the frequency of a modulated carrier while preserving the modulating signal substantially unaltered.
