ABSTRACT:
A variable analog delay line apparatus utilizing a plurality of tapped SAW devices that are connected in series by single pole multi-throw switch units. The amount of delay is determined by the switch throw arm of the switch unit that is associated with the SAW device. The delay times are added serially to obtain the needed delay.
