How to generate sine wave using PWM?

The key to generating a sine wave is the ability to continuously generating a time-varying PWM. Time- varying PWM means that the duty cycle will change from one sample point to another. The duty cycle at each sample point is a representation of the sine amplitude. Two things are necessary in order to accomplish this.

Which method is used to generate sine wave using DAC?

The periodic updating of the DAC with sine wave values causes the output of the DAC to be a sine wave. Another method is by filtering a square wave to get a sine wave. A square wave with frequency equal to the desired sine wave frequency is generated using timers.

What is digital sine wave?

Digital inverters and sine wave inverters are unrelated electrical devices. Digital inverters flip the one and zeros in binary signals. Sine wave inverters use direct current (DC) electricity to simulate alternating current (AC) electricity.
