How Digital to Analogue Converters (DAC) works?

It is very important question in digital electronics that How Digital to Analogue Converters (DAC) works? In our real world most of signals are analogue continues in nature. But if we want to process it further we need to convert these analogue signals in digital signals and after process again we have to convert it in analogue form using Digital to Analogue Converters. The input of a Digital …

Frequency Counter

As name suggest a frequency counter is a special kind of digital circuit that can measure and display the frequency of a signal. In my previous post I discussed on 1) what is a counter? 2) Ripple counter, 3) Asynchronous 3-bit Up Down counter, 4) what is a synchronous counter? You may refer all those to clear your concept …
