Abstract
1,195,188. Phase comparators. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 17 March, 1969 [30 March, 1968], No. 13837/69. Heading H3A. A phase comparator comprises: a gate 9; means 3, 5, 7 and 4, 6, 8 for applying as control signals to the gate, two signals of the same frequency which are derived from the two signals 1, 2 whose phases are to be compared, and which open the gate for a period dependent on the phase difference; a counter 10 connected to the output of the gate; and means 11, 12, 13 for applying, as an input to the gate, signals which are derived from one of the two inputs 1, 2 and which are at a frequency having a predetermined multiple relationship with the frequency of the two gate control signals. The two control signals may be obtained by means of dividers 7, 8, alternatively the dividers may be omitted and a multiplier may be included in the gate input path 11, 12, 13, or in a third alterntive both dividers and a multiplier may be used.
