It's especially effective on delay lines.
An RF delay line is a device that delays the input signals by a certain amount of time. Delay lines are used in a variety of applications such as radars, simulation of communication challenges, FM signal generation, and signal processing, and so on. When looking for a RF delay line, one must review the following specifications. The delay line is an elementary functional unit that models acoustic propagation delay. The function of a delay line is to introduce a time delay between its input and output. The delay line has a time delay equal to the pulse repetition interval, and the received signal and the reference signals are fed to a mixer called the phase detector, whose output is proportional to the phase difference of the two input signals. There are two basic types of delay lines: fixed and variable. A delay line can delay signals by a time interval set by the manufacturer. On fixed delay lines, the delay time is the only delay time that can be set. A variable delay line can del
