WEBA phase-locked loop is a feedback system combining a voltage controlled oscillator (VCO) and a phase comparator so connected that the oscillator maintains a constant phase angle relative to a reference signal. Phase-locked loops can be used, for example, to generate stable output high frequency signals from a fixed low-frequency signal.

Guide to Selecting and Using RS-232, RS-422, and RS-485 Serial
WEBDec 29, 2000 · Three common serial data standards, RS-232, RS-422, and RS-485, are described by specification and electrical interface. Cable termination techniques, use of multiple loads, daisy-chaining of RS-232, conversion of RS-232 to RS-485, conversion of RS-485 to RS-232, and RS-232 port-powered RS-485 conversions are described.
WEBThe op amp common-mode rejection ratio (CMRR) is the ratio of the common-mode gain to differential-mode gain. For example, if a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1V, then the CMRR is X/Y.
Fundamentals of RS-232 Serial Communications - Analog
WEBMar 29, 2001 · RS-232 Specifications. RS-232 is a complete standard. This means that the standard sets out to ensure compatibility between the host and peripheral systems by specifying: Common voltage and signal levels. Common pin-wiring configurations. A minimal amount of control information between the host and peripheral systems.
WEBOPEN-LOOP GAIN. Unlike the ideal op amp, a practical op amp has a finite gain. The open-loop dc gain (usually referred to as AVOL) is the gain of the amplifier without the feedback loop being closed, hence the name “open-loop.”. For a precision op amp this gain can be vary high, on the order of 160 dB (100 million) or more.
WEBModulators (sometimes called balanced-modulators, doubly-balanced modulators or even on occasions high level mixers) can be viewed as sign-changers. The two inputs, X and Y, generate an output W, which is simply one of these inputs (say, Y) multiplied by just the sign of the other (say, X), that is W = Ysign(X).
