Black Sheep Analog Delay

A bucket brigade delay is a discrete-time analogue delay developed in 1969 by Philips Research Labs and consists of a series of capacitance sections. The stored analogue signal is moved along the line of capacitors, one step at each clock cycle. The name comes from an analogy with the term bucket brigade, used for a line of people passing buckets of water. In most signal processing applications, Bucket Brigades have been replaced by devices that use digital signal processing, manipulating sa
