Abstract
A pulse edge detector for detecting edges of a pulse signal in a bit stream. The bit stream, and herewith the pulse signal, is synchronized to a clock having half the resolution of a clock signal used to transmit the bit stream. Falling and rising edges of the synchronized pulse signal are determined. It is further determined whether the falling and rising edges of the pulse signal fall within a first or a second phase of the clock signal. The determined phase result is recorded for further processing by a succeeding circuit such as a counter. By determination of the pulse phase in both phases of the clock pulse, a double resolution pulse edge detector is obtained.
