Abstract
1512254 AFC systems SONY CORP 2 July 1975 [5 July 1974] 27924/75 Heading H3A A frequency synthesizer with reduced response time and improved frequency stability characteristics comprises a VCO 3′, an arrangement 8-10 including an adder 8 and detectors 9, 9′ connected to receive the oscillator output via two signal paths (one direct and one via an ultra-sonic delay line 5) having a relative time delay, and providing an output signal applied as at least part of a control signal for locking the oscillator 3′ to a desired frequency. Frequency stability occurs when the phase shift in the line is an integral multiple of 360 degrees and operation at the different stable frequencies may be selected by a control signal (not shown) applied to the oscillator 3
