Ah, Digital Circuits and Design — the subject that separates the dreamers from the engineers. The one where you start with logic gates and somehow end up questioning your own logic at 2 a.m.
If you’re an engineering student (especially in your second year), you’ve probably heard this phrase before – “Digital circuits are easy, yaar, bas basic logic hai.” And then you meet a 4-variable K-map that refuses to simplify.
Let’s be honest — picking the best digital circuits and design book can feel like trying to debug code written by an alien. But don’t worry, I’ve been there, lost there, and found my way back — with two gems that made everything click.
My favourite Book – Digital Circuits and Design by S. Salivahanan
When I first opened S. Salivahanan’s Digital Circuits and Design, I expected yet another theory-heavy book. But what I found was surprisingly student-friendly — a mix of theory, clear examples, and yes, even some practical insights that make you go, “Oh, so that’s how this actually works!”
Why I Recommend It –
- Covers everything from number systems to sequential logic — no topic left behind.
- Includes Analog to Digital (ADC) and Digital to Analog (DAC) conversion concepts — great if you like connecting theory with real-world electronics.
- Perfect for GATE and NET/JRF aspirants — detailed yet simple.
- Bonus points: Verilog HDL concepts are included, so you’ll step into the world of digital design like a pro.
If you’re entering your second year or just stepping into the realm of logic design, this is a book you’ll want in your backpack (or under your pillow during exams).
Second book is Digital Design with an Introduction to the Verilog HDL by Morris Mano, Michael D. Ciletti
Now, let’s talk about Morris Mano’s Digital Logic Design book — the classic, the legend, the reason many of us still dream in binary.
This book is like that strict-but-cool teacher who explains the basics so well that even flip-flops start to make sense. It’s the kind of book that not only prepares you for GATE and NET but also makes you understand how logic design actually thinks.
Why It’s Still a Favourite –
- Explains logic design from the ground up — binary arithmetic, combinational circuits, sequential logic, memory, and HDL.
- Verilog HDL introduction is smooth — even if you’ve never written a line of hardware code.
- A must-read if you’re serious about core electronics or VLSI.
And let’s be real — once you’ve solved a problem from Morris Mano, you feel like you’ve unlocked a new level in engineering life.
Which One Should You Choose?
Honestly? Both.
Start with Salivahanan for the basics and strong conceptual clarity. Once you’re comfortable, move to Morris Mano for depth and that “I actually understand this!” moment.
Think of it like this – Salivahanan is your friendly guide through the forest, and Morris Mano is the mountain you climb after that. Tough, but worth it.
