Digital filter has a wide field of applications, like
measurement & control, communications, audio, and any other appliances. Unlike
an analog filter using LCR components, a digital filter have no device mismatch,
no thermal change and no aging degradation. Arbitrary characteristics are
derived and it ends up to be compact.
