Digital Logic Class 20: Counters Explained | Asynchronous & Synchronous Counters

Описание: Welcome to Digital Logic Class 20 by Himanshu Kaushik | DigiiMento GATE, NET, CSE Prep. In this comprehensive lecture, we dive deep into the topic of Counters. Initially, we revisit our previous discussion on Registers, Flip-Flops, and Flip-Flop interconversion. We solve essential numerical problems on Registers, including Serial-in Serial-out (SISO) and Serial-in Parallel-out (SIPO) configurations.
Moving forward, we thoroughly explore Counters, particularly Asynchronous (Ripple) and Synchronous Counters. We cover critical concepts such as Mode of Counters, Frequency Divider circuits, and Cascaded Counters, highlighting the differences between Asynchronous and Synchronous Counters in terms of speed, clock triggering, and counting sequences.
