Abstract

This paper describes a new technique for the implementation of wideband Discrete Hilbert Transforms (DHT's) via the use of parallel processing implemented in commonly available lower speed digital hardware. The DHT is a well known method of generating analytic (i.e. complex valued) signals from real valued signals which are sampled at a high rate with an analog-to-digital converter (ADC). The parallel structure involves redundant use of demultiplexed high speed samples in a variable tapped delay line structure.
