sigma-delta converterA circuit that generates a 1-bit pulse density modulated (PDM) signal from analog input. It creates fixed-width pulses in relation to the amplitude of the analog waveform. As the wave amplitude rises, 1's are produced. As it falls, 0's result. If it remains neutral, alternating 01's are created. See PDM and SACD. How to thank TFD for its existence?

| The direct digital, open loop scheme avoids the non-linearity caused by pulse width timing resolution limitations of silicon technology and does not use complex delta-sigma modulation, linearizing feedback loops, DSP error-correction or predictive error-compensating circuitry. Instead of conventional pulse width modulation, Class-T employs multiple signal processing techniques, including adaptive/predicative processing, noise shaping, pre- distortion and delta-sigma modulation.
