Abstract An interleaved digital peak detector has multiple acquisition pipes with each pipe receiving a common input signal. Each acquisition pipe receives a common sample clock signal that is delayed through an analog delay circuit for selectively delaying the sample time of each analog-to-digital converter in the pipe. Each pipe has peak detector, a programmable decimator and a acquisition memory. The maximum and minimum peak detector values from each of the acquisition pipes are compared over the acquisition interval under program control for generating a maximum and a minimum peak detector value over the acquisition interval for the acquisition pipes.
