Pulse Width Modulation (PWM) is a technique used to encode a message into a pulsing signal. It is widely used in various applications, including power electronics, motor control, and communication systems. In PWM, the width of the pulses is varied to represent different values. The duration of each pulse is proportional to the amplitude of the signal being encoded.
The basic principle of PWM involves generating a series of rectangular pulses with a fixed frequency. The
PWM has several advantages over other modulation techniques. It is simple to implement and requires minimal
However, PWM also has some limitations. It can introduce harmonics into the signal, which can cause interference
In summary, PWM is a versatile and efficient modulation technique that is widely used in various applications.
