Difference Between Analog and Digital Signal

A signal is a time-varying entity that carries some information from source to destination. Signals can be of many types such as electrical signal, sound signal, light signal, etc. In electronics, communication, and electrical engineering, we care about the electrical signals the most. For transmission of any other signals, we first need to convert them … Read more

Difference between Latch and Flip flop

In digital electronics, we classify circuits into two primary types which are – combinational circuits and sequential circuits. In the case of combinational circuits, the output depends only on the present input. Whereas, in the case of the sequential circuits, the output depends on the present input as well as the past output(s)/input(s). Due to … Read more

Boolean Algebra Rules & Laws

Boolean algebra is a set of rules which are used to simplify the given logic expression without changing its original functionality. So in this article, we are going to learn about Boolean algebra. The Boolean algebra was invented by George Boole; an English mathematician who helped in establishing modern symbolic logic and whose algebra of … Read more

What are Sequential Circuits?

In Sequential Circuits, the present output depends on the present input as well as past output(s). It consists of a combinational circuit and memory elements. A block diagram of a sequential circuit is shown in Fig.1. It consists of a combinational circuit to which storage or memory elements are connected to form a feedback path. … Read more
