Abstract  Abstract

In a digital wireless subscriber telephone unit for wireless connection with a base station which includes a modem processor whose signal is converted to an analog signal which is then upconverted and filtered to form an IF signal a deglitching circuit for removing glitch spikes occurring during the transition periods from digital signals to analog signals comprising a timing system a detector for detecting the transistion periods in order to control the timing system and a mixer coupled to the output of a D/A converter to mix a blanking signal from the timing system with the analog signal received from the D/A converter during the transistion periods whereby the output of the mixer is returned to an intermediate reference level.
