ABSTRACT:
This variable delay line system includes a variable delay line which has two output ends and a plurality of signal input points at its intermediate points, a means for selecting one of the input points of the variable delay line and for inputting a signal thereto, and a means for switching the signals from the output ends of the variable delay line and for outputting them. Optionally, a fixed delay line can further be included. Thereby, the varibale delay line system has a simple and compact structure and is effective.
