Phase distortion synthesis — is a synthesis method introduced in 1984 by Casio in its CZ range of synths, and similar to Frequency modulation synthesis in the sense that they are both built on phase modulation. Basically a sine wave is played, but by modifying the phase… … Wikipedia
Envelope detector — An envelope detector is an electronic circuit that takes a high frequency signal as input, and provides an output which is the envelope of the original signal. The capacitor in the circuit stores up charge on the rising edge, and releases it… … Wikipedia
Phase detector — A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase locked loop (PLL).Detecting phase… … Wikipedia
Phase velocity — periodic gravity waves on the surface of deep water. The red dot moves with the phase velocity, and is located at a fixed wave phase: the crest for the case shown.The phase velocity (or phase speed) of a wave is the rate at which the phase of the … Wikipedia
Common envelope — The red giant (red, left) fills its Roche lobe (dashed green line) and begins transferring mass to the main sequence star (yellow, right). As the mass transfer accelerates, the core of the massive star (gray) and the main sequence star become… … Wikipedia
ADSR envelope — mdash; over time. The envelope may be a discrete circuit or module (in the case of analog devices), or implemented as part of the unit s software (in the case of digital devices).When a mechanical musical instrument produces sound, the Loudness… … Wikipedia
Continuous phase modulation — Passband modulation v · d · e Analog modulation AM · … Wikipedia
Group delay and phase delay — Group delay is a measure of the time delay of the amplitude envelopes of the various sinusoidal components of a signal through a device under test, and is a function of frequency for each component. Phase delay is a similar measure of the time… … Wikipedia
Slowly varying envelope approximation — In physics, the slowly varying envelope approximation (SVEA) is the assumption that the envelope of a forward travelling wave pulse varies slowly in time and space compared to a period or wavelength. This requires the spectrum of the signal to be … Wikipedia
Träger-Einhüllenden Phase — Die Träger Einhüllenden Phase (TE Phase, engl. carrier envelope (offset) phase, CE phase, CEO phase) ist eine Eigenschaft eines Lichtpulses, die relevant wird, sobald dessen Dauer nur noch wenige Periodendauern beträgt. Die TE Phase ist von… … Deutsch Wikipedia
Absolute phase — refers to the phase of a waveform relative to some standard (strictly speaking, phase is always relative). To the extent that this standard is accepted by all parties, one can speak of an absolute phase in a particular field of application.High… … Wikipedia
