Abstract
The transmission and reception of burst analog signals, such a voice signal, over a TDM system is improved according to the present invention by minimizing discontinuities between the signal at the end of its time slot in one frame relative to the beginning signal at its next time slot in the following TDM frame. In the TDM transmitter, stored digital information transmitted during its time slot is reprocessed during the preceding time slot in the next frame in order to maintain magnitude continuity. In the TDM receiver, the feedback signal to an analog to digital conversion circuit is switched during non-active time slots to follow data being clocked out of a digital storage element at a frame rate such that the data clocked out preceding the next active time slot will correspond to the data present at the end of the preceding active time slot.
