Digital Logic
Revision + PYQsDigital Logic was one of the faster subjects to get through, mostly because a lot of it builds directly on first-year electronics that hadn't fully left my head.
Most of my time here now is PYQ practice rather than fresh learning — mainly K-maps and sequential circuit problems, done under time pressure instead of at leisure.
Topics I'm covering
- Boolean Algebra & K-Maps
- Combinational Circuits — Adders, MUX, Decoders
- Sequential Circuits — Flip-Flops, Counters
- Number Systems & Codes
- Minimization Techniques
PYQ notes
K-map minimization and flip-flop-based sequential circuit questions are the recurring types I drill.
From the journey
Day 5
TCP Timers, a Data Structures Test, and an Unexpected Algorithm Revision
Noticed a gap in algorithm theory while taking a Data Structures test, and used that feedback to plan a weekend revision catch-up.
Day 4
A 60% Score, TCP Diagrams, and One Wrong AI Answer
Took a Digital Logic combinational circuits test, scored 15 out of 25, and identified static hazards as a topic to study.
