: Early chapters introduce number systems (binary, octal, hex), binary arithmetic, and various coding schemes.
Dr. Salivahanan’s Digital Circuits and Design remains the gold standard for undergraduate engineers in the Commonwealth nations. Its methodical approach, hundreds of examples, and exam-oriented structure make it superior to many more expensive international texts.
Ever wondered why your circuit needs a pull-up resistor? This chapter compares transistor-transistor logic (TTL) and complementary metal-oxide-semiconductor (CMOS) families, discussing fan-out, power dissipation, and propagation delay.
