PHYS 31112

>< Type/ Status : Core
>< Title : Electronics
>< Pre-requisites : PHYS 11014
>< Objectives : After successful completion of this course, students will be able to understand the basics of both analogue and digital electronics and their physical principles of operation, and will be able to solve simple problems in analogue and digital electronics including mathematical manipulations.
>< Course Content :

Analogue Electronics
Diodes and applications (half-wave rectifier, full-wave rectifier, voltage-multipliers, detector); Transistors: operation of bipolar junction transistor, modes (active, saturation, cut-off), configurations (common base, common collector, common emitter) and applications of each, static and dynamic characteristics, operating point, biasing and stability of operating point, equivalent circuits and small signal analysis, single and multistage amplifiers and analysis using equivalent circuits, feedback amplifiers (negative, positive and oscillators), Operational amplifiers: feedback-amplifiers (inverting, non-inverting and summing), oscillators, follower, differentiator, integrator, phase shifter, VC and CV converters, comparator.

Digital Electronics
Digital and binary quantities, binary digits, logic levels, digital waveforms, binary, decimal and hexadecimal numbers and their conversions, binary arithmetic, 1’s and 2’s complements of binary numbers, signed integers and arithmetic operations, binary coded decimal, Boolean operations and expressions, laws of Boolean algebra, DeMorgan’s theorems, simplification using Boolean algebra, truth tables, Karnaugh maps, SOP and POS minimisation, logic gates (inverter, OR, AND, NOR, NAND, exclusive-OR and exclusive-NOR), universal property of NAND and NOR gates, implementing combinational logic using NAND and/or NOR gates.

>< Methodology : A combination of lectures and tutorial discussions.
>< Scheme of Evaluation : End of course written examination.
