Abstract

The variable delay line provides a voltage output proportional to the delay of a pulse passed through the delay line. A delay line is positioned as a potentiometer in the bias circuit of a D.C. amplifier.

Delay Line Amplifier

The variable delay line provides a voltage output proportional to the delay of a pulse passed through the delay line. A delay line is positioned as a potentiometer in the bias circuit of a D.C. amplifier.

As the amount of delay is changed by moving the tap on the delay line, the potentiometer provides a variable bias proportionate to the position of the tap, and the D.C. output of the amplifier, which may feed a meter or the like, is a function of the amount of delay. R1, R2 and R3 serve as pulse terminations, C1 and C2 decouple the D.C. current from the pulse terminations and L1, L2, L3 and L4 decouple the pulse from the D.C. current.
