Time division multiplex system suited for burst analog transmission

In a time devision multiplexed (TDM) transmitter in which an input signal is compressed in time before trasnmission to form a compressed signal, at least first and second time slots exist in each TDM frame with the transmitter transmitting said compressed signal during said first slot, a method for minimizing undesired transients comprising the steps of:

• storing digital data corresponding to one frame of said input signal;
• transferring said stored digital data to a means for converting said digital data into an analog signal during said first slot;
• transferring said stored digital data to said converting means during the slot preceding said first during the next frame to maintain magnitude continuity of said input signal from the end of the first slots in one frame to the beginning of first slot in the next frame thereby minimizing undesired transients due to magnitude discontinuities.

A time division multiplexed (TDM) transmitter in which an input signal is transmitted, at least first and second time slots exist in each TDM frame with the tranamitter transmitting said input signal during said first slot, the transmitter comprising:

• means for converting said input signal into a corresponding transmission signal for transmission during said first time slot in a first frame, said transmission signal at the end of said first time slot in said first frame having an associated signal value;
• means for causing said converting means to begin at said associated signal value at the beginning of a first slot in the next frame to minimize discontinuities.

A time division multiplexed (TDM) receiver for receiving a first signal, at least first and second time slots exist in each TDM frame with the receiver receiving said first signal during said first slot, the receiver comprising:

• demodulation means for converting said received first signal into a corresponding output signal, said received first signal at the end of said first time slot in a first frame having an associated signal valve;
• means for causing said demodulation means to begin at said associated signal value at the beginning of a first time slot in the next frame to minimize discontinuities.
