Class D amplifier, also known as switching amplifier is referred to an electronic amplifier in which amplifying devices such as transistors function as electronic switches, unlike other amplifiers in which these devices operate as linear gain units. The signal that is to be amplified is a chain of incessant amplitude pulses, so that the devices which are active can switch back and forth rapidly between a completely non-conductive and conductive state. The analog signal in the process to be amplified is transformed to a series of pulses with the help of pulse density and width modulation or other different methods. The class-D amplifier works by generating a series of square pulses of a fixed amplitude but with varying separation and width, the portion in low-frequency is the actual frequency spectrum whose signal is to be amplified.
