Digital System Design (DSD) covers the foundational principles of modern digital electronics—from basic logic gates to advanced programmable devices. Students will learn how to analyze, design, and optimize both combinational and sequential logic circuits for real-world applications.
Unit-Wise Descriptions
Unit I: Basic Concepts
-
Description: Covers the fundamentals of digital logic, including number systems, Boolean algebra, logic gates, and Boolean expression simplification using Karnaugh Maps (K-Maps) and Quine-McCluskey methods.
Unit II: Combinational Logic Circuits
-
Description: Focuses on designing circuits where the output depends solely on current inputs. Topics include adders, subtractors, multiplexers, demultiplexers, encoders, decoders, and code converters.
Unit III: Synchronous Sequential Circuits
-
Description: Explores time-dependent circuits controlled by a central clock signal. Covers flip-flops, registers, counters, and the design/analysis of Finite State Machines (Mealy and Moore models).
Unit IV: Asynchronous Sequential Circuits
-
Description: Covers sequential circuits that operate without a global clock. Focuses on analysis procedures, transition tables, race conditions, hazards, and asynchronous state machine design.
Unit V: Logic Families and Programmable Logic Devices
-
Description: Compares hardware logic families (TTL, CMOS, ECL) based on speed, power, and noise margin. Introduces programmable hardware structures including PLAs, PALs, CPLDs, and FPGAs.
