Dynamic rf Phase Meter

Abstract
A transistorized phase meter built around a NOR circuit is described. The upper frequency limit is on the order of 4.5 Mc. The use of a flip-flop as a frequency divider extends the usable phase range from 0 to 360°. The resulting ambiguity is corrected by a reset circuit. The deviation from linearity is less than ±1°. The phase modulation frequency bandwidth is 20 kc.
