Introduction
Electronics
and Communication Engineering has evolved far beyond traditional circuit theory
and communication systems. Today, Embedded Systems and VLSI Design form the
technological backbone of intelligent devices, high-performance computing
platforms, automotive control systems, telecom infrastructure, healthcare
monitoring equipment, banking hardware, industrial automation, and
