Patent GB-1307372-A (GB)
Title: Phase controlled oscillators
IPC: H03L7/10
Filed: 1970-05-07
Abstract: 1307372 Automatic phase control circuits FUJITSU Ltd 7 May 1970 [7 May 1969] 22210/70 Heading H3A An automatic phase control system comprises: two phase comparators 7, 8 each fed with a reference signal from input 1 and a signal from oscillator 4; means 11 for providing a phase shift of #/2 to one input of one comparator; a circuit 9 for sensing the polarity of the output from comparator 8; and a circuit 10 for inverting the output of comparator 7 in dependence on the output of circuit 9. The comparator 7 is of the type which gives zero output at #/2 and 3#/2, and by introducing the #/2 phase shift 11, the comparator 8 gives an output of one polarity between 0-# and an output of the opposite polarity between #-2#. The polarity of the output from circuit 9 thus depends on whether comparator 7 is locking at #/2 or 3#/2. An output from circuit 9 is applied to circuit 10 to change the polarity of the reference signal applied to comparator 7 and thus change the polarity of its output. Another output from circuit 9 is applied to circuit 12 to similarly switch the polarity of signal fed from oscillator 4 to output 5. The output from comparator 7 is fed via filter 3 to control the oscillator phase. The circuit 9 may be modified by the inclusion of logic gates and bi-stable circuits, Fig. 4 (not shown), which switch to a "1" or "0" state as the #/2 or 3#/2 lock point is approached.
