A multi-output first-order digital filter structure for VLSI implementation

A multi-output first-order digital filter structure is presented. The overall structure consists of one delay, one multiplier, and four adders. Together with a multi-output second-order digital filter structure, all oddand even-order Butterworth, Chebyshev, and elliptic low-pass, high-pass, band-pass, band-stop, and all-pass digital filters can be designed using a Filter Design Handbook.
