Digital Design using Verilog HDL
Covers synchronous and asynchronous FSMs in the design of both simple and complex systems, and Petri-Net design techniques for sequential/parallel
control systems. Chapters on Hardware Description Language cover the widely-used and powerful Verilog HDL in sufficient detail to facilitate the
description and verification of FSMs, and FSM based systems, at both the gate and behavioural levels.

Power System Relaying
Features problems to be worked through at the end of each chapter, Analyzes system performance through oscillographs and alarms schemes, Discusses in
detail the emerging technologies of adaptive relaying, hidden failures, wide area measurement, global positioning satellites and the pecific
application of digital devices. Power System Relaying offer comprehensive and accessible coverage of the theory and fundamentals of relaying and have
been widely adopted on university and industry courses worldwide.
