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

PSK, FSK), digital modulation techniques (BPSK, QPSK, QAM), differential modulation. Demodulation and signal detection: Gaussian basics,

Optical metrology systems offer many attractive measurement features. * 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. While the digital demodulation is the most interesting part of the project, the larger and more complicated part of the project is the front end of the receiver. The front end is used to down convert the RF signal to a frequency band that is possible to sample using the A/D converters on the NEXYS board. If the demodulation had to be done in hardware, this would be the approach to use. But in the System Five, the demodulation is done in software using Digital Signal Processors (DSPs), and the complex exponential is used instead.

The changes in the carrier signal are chosen from a finite number of M alternative symbols (the modulation alphabet). and demodulation schemes.

Here, the successful experimental realization of AM, FM, and digital demodulation with suspended single-walled carbon-nanotube resonators in a field-effect transistor configuration is reported. The crucial role played by the electromechanical resonance in demodulation is clearly demonstrated.
