pulse-power amplifier
1Pulse-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… …
2amplifier — Synonyms and related words: attenuator, audio frequency tube, ballast regulator, ballast tube, beam switching tube, convertor, current regulator, damper, detector, discriminator, doubler, ear trumpet, electronic hearing aid, focus tube, generator …
3Electronic amplifier — A practical amplifier circuit An electronic amplifier is a device for increasing the power of a signal. It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In… …
4Class-D amplifier — Block diagram of a basic switching or PWM (class D) amplifier A class D amplifier or switching amplifier is an electronic amplifier where all power devices (usually MOSFETs) are operated as binary switches. They are either fully on or fully… …
5Switching amplifier — A switching amplifier or class D amplifier is an electronic amplifier which, in contrast to the active resistance used in linear mode AB class amplifiers, uses switching mode of transistor to regulate power delivery. The amplifier, therefore,… …
6Optical power meter — in use An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually… …
