Km Jd · 1973
Summary An optimal FIR low-pass filter can now be designed where any four of the five parameters N, Fp , F,, ti1, and ti2 are specified, and the remaining parameter is chosen so as to meet or exceed specifications on all gven parameters. A set of simple, approximate formulas was given for obtaining initial estimates of the unspecified parameter. Finally, simple iterative rules
