hi everybody
I'm working on mc3356 FSK receiver . I have a problem with quadrature detector section. what i have understood : this section must make a voltage (on pin 13 or 12 in Fig.1) that is proportional to the difference between input signal frequency (on pin 7) and frequency determined by quadrature tank . (is correct??) . but what happen is that voltage on pin 13 doesn't change by input frequency changing. where is my wrong???
thanks
