Adjustable signal delay circuit comprises a two signal delay members, delay measurement member, subtractor and amplifer connected to permit delay adjustment and control

摘要

Circuit for adjustable delay of a signal comprises a controllable delay member (1) with signal input, signal output and control input. Connected to the controllable delay member are a further delay member (2), a delay measurement member (3), a subtractor (4) and an amplifier (5). The various elements are connected to permit control, measurement and adjustment of the signal delay. An independent claim is made for a circuit for automatic calibration of phase measurement elements.
