The Science of Everything Podcast

In this third part of the series on computers I begin with an overview of Boolean algebra, including a discussion of key logic functions such as NOT, AND, and OR, and also discuss how CMOS logic gates implementing these functions are fabricated from transistors. I then survey the wide variety of logic components used in electronic circuits, including the multiplexor, adder, tristate buffer, flip-flops, comparator, and clock generator, and discuss the functions fulfilled by these devices in modern computers.
