Flip-Flops & Latches – Ultimate guide – Designing and truth tables

One of the most integral parts of modern digital electronics and gadgets is the memory. Storage is expensive. And flip-flops are the building blocks of storage.

Counters - Synchronous and Asynchronous up, down and up-down counters

November 17, 2018

Counters – Synchronous, Asynchronous, up, down & Johnson ring counters

Counters perform the function of counting events in digital electronics and digital circuits. There are many types of digital counters. We will take a look at a few important ones and understand the process of designing them.

parity generators and parity checkers

October 14, 2019

Parity Generator and Parity Checker

In digital systems, during data transmission and processing, data gets distorted. This is due to the noises added to it. Such noises change 0s to 1s and 1s to 0s. Annoying, right? It is necessary to identify and remove these errors. One of the most widely used error detection techniques for transmission of data for […]
