Digital Amplification Basically, a digital (Class D) amplifier takes an incoming analog signal and converts it into a digital representation comprised of pulse widths. Although there are a number of ...

The voltage drop across the 555’s output transistors increases rapidly if the output current is much above 100mA. Also see : Active-filter circuit and oscilloscope inspect a Class D amplifier’s output ...

Testing a Class D amplifier poses more difficulties. The amplifier's output comprises a PWM (pulse-width-modulated) signal that swings between ground and the supply voltage at a frequency that's ...

Class D is a digital-like amplifier that works by turning a transistor fully on or off, but the "D" technically does not stand for digital. See Class D amplifier.
