4 Bit Asynchronous Counters: Working and Applications

An Asynchronous Counter, also known as a Ripple Counter, is a type of digital counter where the clock signal is applied to only the first flip-flop, and subsequent flip-flops toggle based on the output of the previous one. This introduces a propagation delay, making it “asynchronous.” Asynchronous Binary Counter Terminology Here’s a breakdown of all […]

4 Bit Synchronous Counters: Working and Applications

A 4-bit synchronous counter using JK flip-flops is a sequential circuit that counts in a binary sequence (0000 to 1111), with all flip-flops receiving the clock pulse simultaneously, eliminating propagation delays found in asynchronous counters. Synchronous counters offer faster and more reliable counting operations, making them ideal for applications requiring precise timing. This article explores […]
