Abstract:

The purpose of this report is to design and select MTI filters which will satisfy given specifications with tolerable quantization effects and a minimum amount of hardware. Programs are developed to design low-pass, high-pass, band-pass and band-reject filters of types Butterworth, Chebyshev I, Chebyshev 2 and elliptic. The transfer function is factored into second-order and first-order sections and five realizations are considered direct, canonical, modified canonical, coupled canonical and Micks. Binary fixed-point twos complement arithmetic is assumed. A simulation program is developed for a typical nonrecursive filter. Programs are developed to design, evaluate, and select high-pass and band-pass MTI recursive filters. It is shown that Chebyshev I, Micks realization, is the recommended choice for a typical MTI filter. Author
