    en.wikipedia.org/wiki/Delta-sigma_modulation

    Delta-sigma (ΔΣ; or sigma-delta, ΣΔ) modulation is an oversampling method for encoding signals into low bit depth digital signals at a very high sample-frequency as part of the process of delta-sigma analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

    English: Delta-sigma modulation loop model with quantization noise in the Laplace (s) domain. Integration become 1/s, and the quantization process can be modeled as simply adding noise. Integration become 1/s, and the quantization process can be modeled as simply adding noise.

    en.wikipedia.org/wiki/Sampling_(signal_processing)

    The Whittaker–Shannon interpolation formula is mathematically equivalent to an ideal low-pass filter whose input is a sequence of Dirac delta functions that are modulated (multiplied) by the sample values. When the time interval between adjacent samples is a constant (), the sequence of delta functions is called a Dirac comb.

  6. Delta modulation - Wikipedia

    en.wikipedia.org/wiki/Delta_modulation

    Delta modulation (DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance. DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples is encoded into n-bit data ...

    English: This is a block diagram of a simplified Delta Sigma ADC and is my own work drawn using "Inkscape" a free svg editor. It was drawn to illustrate a description of the functioning of the so-called Delta Sigma ADC which appears in the overall article on Delta Sigma modulation.

    English: Delta-Sigma Modulation ADC (top) and DAC (bottom) comparison block diagram. The actual delta-sigma modulation stage in each is identified by a curly bracket. Green arrows indicate analog signals, and blue arrows indicate digital signals.

  9. Pulse-width modulation - Wikipedia

    en.wikipedia.org/wiki/Pulse-width_modulation

    Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an electrical signal.
