Abstract
1,224,069. Automatic frequency control. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. 13 Dec., 1968 [15 Dec., 1967], No. 59512/68. Heading H3A. A polyphase system, the waveform of which can be programmed as desired, and the frequency and phase of which can be modulated, uses electronic samplers driven by ring counters and is characterized in that:- (a) For each phase there is provided a voltage controlled oscillator 18, 19, 20, an n-stage ring counter 10, 11, 12, a sampler 13, 14, 15 and an amplifier 21, 22, 23, the inputs of the samplers being connected to a crossbar distributer 16 having a specific voltage associated with each crossbar. (b) Bi-stable circuits 24, 25 are connected between pairs of counters 10, 11, 12 to provide a phase control signal. (c) Means 26, 27 are provided to form from the phase control signal a further signal V ist which is compared with a reference signal U soll to provide an error signal for controlling the associated oscillator 19, 20. Appropriate stages are selected on counters 10, 11 to provide antiphased signals for switching bi-stable circuit 24 to its » set » and » reset » states respectively, thus producing a square wave output signal having a mark/space ratio indicative of the phase relationship of the signals in the two channels R.S. This signal is processed in units 26 to provide the signal V ist dependent on the phase relationship. In the event of an input pulse to the counters being omitted, a logic circuit (31, Fig. 3, not shown) controls a circuit (30) to feed a pulse back from the output to the input. In order to ensure that no more pulses are contained in the counter 10 when a pulse has reached the output, a quenching circuit (33, 34) clears all stages except the first and last.
