modulation amplifier
1Modulation transformer — A modulation transformer is an audio frequency transformer that forms a major part of most AM transmitters. The primary winding of a modulation transformer is fed by an audio amplifier that has about 1/2 of the rated input power of the… …

7Delta-sigma modulation — Delta sigma (ΔΣ; or sigma delta, ΣΔ) modulation is a method for encoding high resolution or analog signals into lower resolution digital signals. The conversion is done using error feedback, where the difference between the two signals is… …
8Class-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… …
9Switching 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,… …
10Polar modulation — is analogous to quadrature modulation in the same way that polar coordinates are analogous to Cartesian coordinates. Quadrature modulation makes use of Cartesian coordinates, x and y . When considering quadrature modulation, the x axis is called… …
