Through proper use of a Hamming window, approximate relationships are established among the coefficients of half-band FIR filters, which may be realised conveniently as delta modulation (DM) filters by simple and economical hardware. The procedure is demonstrated by means of two design examples. Experimental results confirm the theoretical predictions.
