The bilateral band modem circuit composed of NE561B


Posted on Feb 6, 2014

In the figure is the bilateral band modem circuit composed of NE561B. The loading frequency of the input modulating signal is f0=1MHz. When the AM modulation signal is added on the input terminal of the multiplier, it is also added on the phase detection circuit by Rv1, CY1, Y2 and CY2, and it sets the VCO frequency of PLL at f0..
