ABSTRACT:
Waveform inputs are sampled to provide vector inputs which are coupled to respective ones of a plurality of series connected time delay stages in a processing circuit. Each vector is weighted, or amplified, and time delayed by each stage between its input point and the circuit output. Each stage has switched capacitors and an operational amplifier. The delay of each stage is the period of the capacitor switching frequency. All of the components in the stages and vector input circuitry are solid state switches, capacitors or operational amplifiers and therefore are especially suitable for integration in a monolithic or film substrate. The circuit is particularly adapted to beam steering a plurality of waveform inputs from an array of hydrophones.
