555 Timer PWM Audio Amplifier. The “555” integrated circuit is a general-purpose timer useful for a variety of functions. In this 555 audio PWM project, we explore its use as an astable multivibrator. The ubiquitous 555 timer IC handles audio signals in its own pulse-width modulation (PWM) way. Here, the 555 IC works in astable mode.

Fig. 11: Circuit Diagram of Pulse Width Modulation (PWM) The 1M ohm resistor is used to adjust the amplitude of the sine wave signal generated by the WBO. The amplitude of the sine wave should be adjusted in such a way that it matches with the amplitude of the ramp signal generated. The image of PWM circuit wired in the breadboard is given below:

Therefore, a tank circuit is needed to recover the negative half of the pulse to complete the whole waveform. At this point, the RF carrier amplitude is constant. With the presence of an audio signal, the low-level audio will be amplified by the push-pull modulator tubes to produce the high-level audio at the output of the modulation transformer.
