ABSTRACT:
A digital quartz stabilized FM discriminator which is linear and temperature independent and frequency stable and includes a circuit having a phase comparator which receives an input signal and an input from a reversible divider (3) which produces the angular frequencies f.sub.u and f.sub.o of the discriminator. The reversible divider divides a quartz stabilized reference frequency signal under control of the output signal from the phase comparator. A discriminator output signal is obtained by passing the output signal of the phase comparator through a low pass filter.
