Data Transmission, Conversion, and Storage (A9404)

This lesson demonstrates the use of data transmission circuits, digital-to-analog and analog-to-digital converter circuits, and teaches different types of memory.

Prerequisites

This lesson is designed for participants familiar with AC/DC theory, binary numbering systems, and parallel and serial data. A basic understanding of logic gates and flip-flop circuits, and the use of pin connection and wiring diagrams is also required.

Description

This lesson demonstrates the use of data transmission circuits, including multiplexer and demultiplexer circuits. The lesson explains digital-to-analog and analog-to-digital converter
circuits and teaches different types of memory. Troubleshooting of data transmission circuits is also performed.

Objectives

State the functions of a multiplexer. Trace the logic in simplified and complex multiplexer and demultiplexer circuits. Identify the pins used to input, output, and address data for multiplexer and demultiplexer chips. Determine if a multiplexer or demultiplexer chip is functioning properly. Understand the operation of a digital-to-analog and analog-to-digital converter circuit. Understand the operation of a counter type analog-to- digital converter circuit. Read and write data to a specific memory address. Distinguish between rom and ram, and between prom, eprom and earom.
