CIRCUIT DE PRODUCTION D'IMPULSIONS

摘要

The generator includes an address generator (29) which synthesises address signals for a memory (25) whose words are read at cyclically repeated instants to form a first digital signal generator. An address inverter (37) inverts the addresses of words read in the memory and a comparator (41) compares the inversions to the preset value and produces a comparison signal. A distribution circuit delivers, as a function of the comparison signal, a signal to maintain a synthesised address. The distributor has a multiplexer (51) controlled by the comparison signal and receiving first and second instruction signals to transmit instruction signals to an address counter (31).
