One-bit digital signal transmission device

摘要

The transmission device (1) is intended for a 1 bit analogue audio signal (2), transmitting it after the sigma delta modulation (3) along the transmission stretch (8). The system includes other units. After the sigma delta modulation there is a unit (4) for modulating the phase of the 1 bit audio signal (S1) and the unit (9) for demodulating the phase-modulated signal (S3) from the phase modulator (4). This phase modulator consists of a D-latch (5) with a flip-flop unit and a change-over switch (6) and the process is fully explained.
