Beschreibung
Zusammenfassung:	A digital timing recovery circuit operative upon digital samples of the input signal to a data receiver provided at the sample rate to produce a clock correction signal at the symbol rate utilizing a digital periodic filter providing a double restrictive bandpass characteristic about the band edge frequencies and outputting to a nonlinear device followed by a digital sampling filter designed to require only addition and subtraction of the nonlinear device outputs.
