摘要：
This work presents a fast algorithm for computation of the running discrete Hartley transform (RHT) coefficients. The method is based on the close relations between the running discrete Fourier transform and the RHT. For N point RHT only 2N real multiplications are needed. The method is faster than some other digital filter approaches. The outcome of the algorithm enables also fast computation of the running discrete Fourier transform coefficients.
