11Audio amplifier — An audio amplifier is an electronic amplifier that amplifies low power audio signals (signals composed primarily of frequencies between 20 hertz to 20,000 hertz, the human range of hearing) to a level suitable for driving loudspeakers and is the… …
12Switching 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,… …
13Valve amplifier — A valve amplifier or tube amplifier is a type of electronic amplifier that make use of vacuum tubes instead of solid state semiconductor devices (such as transistors). As any other electronic amplifier they serve to increase the power and/or… …
14Valve audio amplifier — A valve (UK) audio amplifier or vacuum tube (US) audio amplifier is a valve amplifier used for sound recording, reinforcement, or reproduction. Until the invention of solid state devices such as the transistor, all electronic amplification was… …
15Class-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… …
16Buffer amplifier — A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer. Figure 1: Top: Ideal voltage… …
17Valve 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… …
18Direct coupled amplifier — Direct coupled, also known as DC amp , refers to a type of amplifier. In this type of amplifier, the output of one stage of the amplifier is connected to the input of the next stage directly without using any reactive components like capacitors,… …
19Doherty amplifier — The Doherty amplifier is a modified class C radio frequency amplifier invented by William H. Doherty in 1936. The amplifier is usually configured as a grounded cathode, carrier peak amplifier. Using two vacuum tubes, or two power transistors in… …
20Frequency response — is the measure of any system s spectrum response at the output to a signal of varying frequency (but constant amplitude) at its input. In the audible range it is usually referred to in connection with electronic amplifiers, microphones and… …
