  • Phase detector having a 360 linear range for periodic and aperiodic input pulse streams
    Patent number: 3986125
    Abstract: A phase detector comprising three bistable flops and a NAND gate interconnected to respond to a data input pulse stream and a controlled square wave clock pulse stream to provide, in response to each data pulse, a reference pulse having a width equal to one-half the clock pulse period and a variable pulse having a nominal width equal to that of the reference pulse and a proportionately greater or lesser width according to the direction and amount of displacement of the data pulse from the center of the clock period in which it occurs.
