DIGITAL ELECTRONICS: LOGIC AND CLOCKS
physicscourses.colorado.eduDIGITAL LOGIC GATES The flow of digital signals is controlled by transistors in various configurations depending on the logic family (see H&H 8.09 for details). For most purposes, we can imagine that the logic gates are composed of several ideal switches with just two states: OPEN and CLOSED. The state of a switch is controlled by a digital signal.

Verilog HDL: A Guide to Digital Design and Synthesis
robo-tronix.weebly.comdigital circuits were designed with vacuum tubes and transistors. Integrated circuits were then invented where logic gates were placed on a single chip. The first integrated circuit (IC) chips were SS1 (Small Scale Integration) chips where the gate count was very small. As technologies became sophisticated, designers were
