Abstract
A wideband signal delay line network comprises at least respective end terminals and an intermediate terminal. One of the end terminals and the intermediate terminal are coupled to a source of wide bandwidth composite signal, and are arranged to provide a signal time delay therebetween substantially equal to NT/2, where N is an odd integer and T is the reciprocal of a selected frequency at which it is desired to provide a desired amplitude response (e.g., attenuation or null) of the composite signal. A combined signal appearing at the intermediate terminal is representative of the composite signal coupled to the intermediate terminal and the composite signal coupled to the one end terminal, the latter signal being delayed relative to the composite signal coupled to the intermediate terminal. The combined signal is coupled via the remaining end terminal to utilization means. An illustrative utilization means comprises an amplitude peaking circuit accepting signals from the remaining end terminal and additional intermediate terminals of the delay line network.
