What the quiz covers
Digital logic is part of B.Tech CSE and ECE first-year and second-year syllabi, and a regular GATE topic. The 25 questions are grouped into 10 areas, shown above each question: Gates, Boolean algebra, Number systems, K-maps, Combinational, Sequential, Counters, Basics, Codes, Logic families.
A sample question explained
"In a JK flip-flop, J = K = 1 makes the output" The answer is Toggle. Fixes the SR invalid state. The JK flip-flop's toggle case is exactly what makes it useful for building counters.

Study tips
- Simplify each Boolean question with a K-map as well as with laws, and check they agree.
- Practise binary, hex and 2's complement conversions until they're quick.
- Aim for at least 20 out of 25 on two separate attempts before you treat Digital electronics as revised; one lucky score can hide gaps.
Questions and options are shuffled on each attempt, so a retake is a fresh test. The Digital electronics questions were written by Uncodemy for practice; they aren't copied from any exam or company test.
