• 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

• Signal integrity — or SI is a measure of the quality of an electrical signal. In digital electronics, a stream of binary values is represented by a voltage (or current) waveform. Over short distances and at low bit rates, a simple conductor can transmit this with… …   Wikipedia

• Signal edge — Signal edges shown in rectangular pulse amplitude modulation with polar non return to zero, inverted coding waveform In electronics, a signal edge is a transition in a digital signal from either low to high (0 to 1) or high to low (1 to 0). It is …   Wikipedia

• Pulse generator — Pulse generators can either be internal circuits or pieces of electronic test equipment used to generate pulses. Features Simple pulse generators usually allow control of the pulse repetition rate (frequency), pulse width, delay with respect to… …   Wikipedia

• Pulse-position modulation — is a form of signal modulation in which M message bits are encoded by transmitting asingle pulse in one of 2^M possible time shifts. This is repeated every T seconds, such thatthe transmitted bit rate is M/T bits per second. It is primarily… …   Wikipedia

• Clock synchronization — is a problem from computer science and engineering which deals with the idea that internal clocks of several computers may differ. Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by …   Wikipedia
