Abstract
1277628 Phase comparators ALLMANNA SVENSKA ELEKTRISKA AB 13 Oct 1969 [14 Oct 1968] 50173/69 Heading H3A A phase comparator comprises: first and second gates 12, 13 with one input 14, 16 of each connected to a respective input signal U or I and a second input 15, 17 connected to the output of the other; a third gate 20 having one input 21 connected to the output of the first gate 12 and the other input 22 connected to input 16 of the second gate 13; an integrator 25 connected to the output of gate 20; and a level switch 26 connected to the output of integrator 25 and arranged to operate when the phase difference between the two inputs passes a predetermined value. In the embodiment of Fig. 1, gates 12, 13 are NOR gates, gate 20 an AND gate, and an inverter 23 is included in the connection between input 16 and input 22. In an alternative embodiment, Fig. 3 (not shown), all three gates are NAND gates and the inverter (40) is included in the connection between the output of the first gate and the other input to the third gate.
