The recursive Hartley transform, which is shown not only to have the ability to calculate the running DHT (discrete Hartley transform) but also the efficiency to calculate the running DFT (discrete Fourier transform), is derived. Furthermore, based on this derived recursive formula, the recursive Hartley filter (RHF) can be derived accordingly, and by use of the recursive Hartley filter, a real-time DHT analyser can be constructed.
