Operational amplifier applications — This article illustrates some typical applications of operational amplifiers. A simplified schematic notation is used, and the reader is reminded that many details such as device selection and power supply connections are not shown. Contents 1… … Wikipedia
Electronic 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… … Wikipedia
Class-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… … Wikipedia
Valve RF amplifier — A valve RF amplifier (UK and Aus.) or tube amplifier (U.S.), is a device for electrically amplifying the power of an electrical , typically (but not exclusively) radio frequency signals.Low to medium power valve amplifiers for frequencies below… … Wikipedia

Bode plot — ; the straight line approximations are labeled Bode pole ; phase varies from 90° at low frequencies (due to the contribution of the numerator, which is 90° at all frequencies) to 0° at high frequencies (where the phase contribution of the… … Wikipedia
Musiques de Naruto — Cet article présente les différents disques liés aux adaptations du manga Naruto. Pour partie, il s’agit des bandes originales des séries télévisées, des films et des OAV, mais l’article compte aussi les singles des chansons ayant servit de… … Wikipédia en Français
Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… … Wikipedia
Bridged and paralleled amplifiers — Multiple electronic amplifiers can be connected such that they drive a single floating load (bridge) or a single common load (parallel), to increase the amount of power available in different situations. This is commonly encountered in audio… … Wikipedia
Step response — The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the… … Wikipedia
Clipping (audio) — For shortening of voice snippets due to failures in voice activity detection, see squelch and voice activity detection. The altered peaks and troughs of the sinusoidal waveform displayed on this oscilloscope indicate the signal has been clipped.… … Wikipedia
