Chaotic behaviour of sigma-delta modulators.
Original language description
The paper deals with sigma-delta modulators and with their chaotic behaviour. The presence of chaos is usually considered to be undesirable, it can be put to good use in modulators. It is showed that chaos can be used to destabilize undesirable limit cycles which in audio applications manifest as objectionable tones. It was found that the amount of chaos introduced in the modulator must be sufficient to adequately destabilize troublesome limit cycles, yet be small enough to ensure proper operation of the modulator.
