There are two phase demodulation algorithms that are presently used: Digital Zero Crossing (DZC) and Digital Phase Quadrature (DPQ).

Other articles where Digital signal modulation is discussed: telecommunication: Digital modulation: In order to transmit computer data and other digitized information over a communications channel, an analog carrier wave can be modulated to reflect the binary nature of the digital baseband signal. Demodulation of FM Waves The demodulation process of FM waves is exactly opposite to that of the frequency modulation.

The down mixing operation multiplies the RF-signal with a complex vector with unit length, * Demodulation is defined as a recovery of a waveform (band pass pulse) and detection is defined as decision-making regarding the digital meaning of that waveform. 2.3 Linear Modulation Techniques * Digital modulation techniques may be broadly classified as linear and non-linear.

There are many types of modulation so there are many types of demodulators. Digital demodulation requires bit-period synchronization; the receiver must be able to identify the boundaries between adjacent symbols. Binary-phase-shift-keying signals can be demodulated via multiplication followed by integration. The reference signal used in the multiplication step has the same frequency as the transmitter’s carrier. Digital modulation relies on digital signal processing, such as digital-to-analog converters (DACs) at a receiver and analog-to-digital converters (ADCs) at a transmitter to transform analog information (e.g., audio or video) into a digital form that can then be represented by varying the characteristics of a carrier wave. A Digital Demodulator is an electronic devices that take a modulated signal, whether it is 8VSB, QAM, or QPSK, and demodulates it into its base format that can be either an analog format (such as audio/video) or a digital format (such as ASI, or SDI,Read More into two portions, the analog FM front end and the digital demodulator.
