It is wired in monostable mode, and the pulse width is varied according to input voltage.

    load using an H-bridge. If this voltage needs to be boosted from the DC source, it can be accomplished either before the AC stage by using a DC-DC boost converter, or after the AC stage by using a boost transformer. The inverted signal itself is composed of a pulse-width-modulated (PWM) signal which encodes a sine wave. ECE 2C Laboratory Manual 4 Infrared PWM Transmitter Overview In this lab you will construct a circuit to produce a 40kHz analog pulse-width-modulator (PWM), to be used later in our one-way analog audio communication link. Later we will combine this modulator with the microphone circuit from am earlier lab to form a complete IR audio transmitter.
