UNDERSTANDING PWM

UNDERSTANDING

Pulse Width Modulation (PWM), is a technique that can be used to create analogue from digital! Using digital electronics to create a square wave, a signal can be created that repeatedly alternates between an ON and OFF state. This pattern can range between 0V and the supply voltage. This is achieved by varying the period…

UNDERSTANDING ADC

UNDERSTANDING

Humans live in an analogue world but computers are digital. Therefore, if we wish to measure elements of our analogue world, we need a way of converting these measurements to digital. This is the role of the process known as Analogue to digital conversion (ADC). With digital signals, we often deal with binary signals, such…
