Digital Logic Design (DLD) Complete Course - Design a 3 Bit Synchronous Up Down Counter using T Flip Flops

In this video, we design a 3-bit synchronous up/down counter using T flip-flops. The unique feature of this counter is the control input 'M', which decides the counting direction: When M = 0, the counter counts up When M = 1, the counter counts down This design is explained step-by-step with: ✔ State transition table ✔ Flip-flop input equations ✔ Excitation table for T flip-flops ✔ Simplification using Karnaugh Maps (K-maps) ✔ Final logic diagram of the counter This is a must-watch for Digital Logic Design (DLD) students preparing for quizzes, assignments, or final exams. It’s also helpful for understanding how control inputs influence sequential circuits. 🔔 Subscribe to Fakhar STEM Sphere for more digital design tutorials and exam-focused solutions. ✅ The Channel link is below 👇👇👇 👉 https://www.youtube.com/channel/UCWAiAV3m08lldG31uEfFuEw?sub_confirmation=1 🟨🟥🟩 Feel Free to ask any questions in the comment section.
