Pulse Width Modulation – What is it?

Anish August 17, 2013 11 Comments
The good definition of Pulse Width Modulation (PWM) is in the name itself. It means modulating/varying the width of the pulse (Not the frequency). To best understand what PWM is, let us first see some basic terminologies. Microcontrollers are intelligent digital components which live on binary signals. Best representation of a binary signal is a square wave. The following diagram explains the basic terminologies associated with a square wave signal. As the shown in the above diagram, the important...

Half adder

admin March 29, 2012 34 Comments
Half adder circuit. To understand what is a half adder you need to know what is an adder first. Adder circuit is a combinational digital circuit that is used for adding two numbers. A typical adder circuit produces a sum bit (denoted by S) and a carry bit (denoted by C) as the output. Typically adders are realized  for adding binary numbers but they can be also realized  for adding other formats like BCD (binary coded decimal, XS-3 etc....

In this article, learn about Ripple carry adder by learning the circuit. A ripple carry adder is an important digital electronics concept, essential in designing digital circuits. Ripple carry adder circuit. Multiple full adder circuits can be cascaded in parallel to add an N-bit number. For an N- bit parallel adder, there must be N number of full adder circuits. A ripple carry adder is a logic circuit in which the carry-out of each full adder is the carry in of...

Flip Flop Conversion

john August 11, 2018 66 Comments
In this article, let’s learn about flip flop conversions, where one type of flip flop is converted to another type. For the conversion of one flip flop to another, a combinational circuit has to be designed first. If a JK Flip Flop is required, the inputs are given to the combinational circuit and the output of the combinational circuit is connected to the inputs of the actual flip flop. Thus, the output of the actual flip flop is the...
