Abstract
An electromagnetic variable delay line system in which the change in the output impedance of the delay line as its delay time is varied is compensated by an electronic device such as a field effect transistor which is connected across the output end of the variable delay line system. Therefore, generation of undesirable reflected waves can be prevented and high speed signals can be processed without distorting the signals.
