Discrete Hartley Transform (DHT) is one of the transform used for converting data in time domain into frequency domain using only real values.DHT can be used for highly modular and parallel processing of data in VLSI applications.We have proposed a new algorithm for calculating DHT of length 2 N , where N=3 and 4.We have implemented multiplier as an improvement in place of simple multiplication used in conventional DHT.This paper gives a comparison between conventional DHT algorithm and proposed DHT algorithm in terms of delays and area.
