2-Bit Synchronous Up Counter Design Using SR Flip-Flop
In this Digital Electronics tutorial, we design and implement a 2-bit synchronous up counter using SR flip-flops with a positive-edge triggered clock.
This video explains the complete step-by-step process including truth table, state diagram, next state equations, Karnaugh map simplification, and final logic circuit implementation.
This tutorial is very useful for:
• ECE students
• Digital Electronics learners
• VLSI beginners
• Exam preparation (GATE, university exams)
• Sequential circuit design understanding
📌 Topics Covered:
✔ What is a synchronous counter
✔ 2-bit up counter operation
✔ SR flip-flop basics
