Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… … Wikipedia
Pulse-width modulation — (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load. PrinciplePulse width modulation uses a square wave whose pulse… … Wikipedia
Modified Frequency Modulation — This article is about Modified Frequency Modulation. For other uses of MFM, see the MFM (disambiguation). Modified Frequency Modulation, commonly MFM, is a line coding scheme used to encode the actual data bits on most floppy disk formats,… … Wikipedia
Delta modulation — Principle of the delta PWM. The output signal (blue) is compared with the limits (green). These limits correspond to the reference signal (red), offset by a given value. Every time the output signal reaches one of the limits, the PWM signal… … Wikipedia
