Day1 02.Introduction

This document provides a brief history of digital logic and programmable logic devices from the 1960s to present. It discusses the evolution of logic families from TTL to CMOS and the development of early programmable logic devices by companies like Altera and Xilinx. It also summarizes binary number systems, Boolean algebra, and logic design concepts like addition, subtraction, and two's complement representation. The rising costs of digital design are noted as well as how logic problems can be solved using programmable logic devices.
