DIGITAL ELECTRONICS

This page collects 41 digital electronics questions taken from 2 BEU semester 4 papers, 2023 to 2024 — about 21 questions in a typical paper. They are sorted into the 5 modules of the syllabus, so you can revise a topic across every year at once instead of working through papers one at a time. 1 of them has a worked solution.

What these papers actually ask

Module 1: Fundamentals and Logic Families is the heaviest module in this archive at 32% of every question recorded, and it has come up in both papers. Together with Module 2: Combinational Circuits, the two account for 61% of the archive.

4 modules have appeared in both papers — Module 1: Fundamentals and Logic Families, Module 2: Combinational Circuits, Module 3: Sequential Circuits, Module 4: A/D and D/A Converters. A module that turns up every year is a safer use of revision time than one with the same question count concentrated in a single paper.

How the marks are split

Questions in this archive carry 4 different mark values. The most common is the 2-mark question, with 19 of them recorded — worth knowing before you decide how much depth to practise at.
