Improved zero-crossing-detector circuit designed for precisely measuring difference between frequencies of two frequency-standard signal sources. Contains low-bandwidth first-stage amplifier and three limiting amplifiers, each "squares" signal bit more. Crosstalk eliminated and jitter reduced to about 10 to the negative 7th power microseconds.
