Abstract

1529549 Automatic frequency control SIEMENS AG 26 July 1977 [17 Sept 1976] 31203/77 Heading H3A In an a.f.c. loop for locking a controlled oscillator 4 to a crystal controlled reference source 1, the output from the reference source 1 is fed via a divider or multiplier 2 to a mixer 4<SP>1</SP> in the controlled oscillator and the output from the mixer is compared with a harmonic or subharmonic of the reference signal in a comparator 6 to produce the required control signal for the oscillator 4.
