Codes, Encoders, Decoders, and Flip-Flops (A9402)

Learn the concepts behind codes, encoders, and decoders and explains how to troubleshoot these circuits.

Prerequisites

This lesson is designed for participants familiar with AC/DC theory, logic gates, and binary numbering systems. A knowledge of pin connection diagrams and wiring diagrams is also required.

Description

This lesson discusses codes, encoders, and decoders and explains how to troubleshoot these circuits. In addition, the lesson addresses the operation and troubleshooting of flip-flops.

Objectives

Convert between BCD and decimal numbers. Identify and describe the function of active low inputs and outputs. Explain the functions of pins on an encoder and the operation of a seven segment LED display. Determine whether encoder and decoder circuits are functioning properly. State the difference between combinational and sequential logic circuits. Describe the operation of R-S flip-flops, D flip-flops, and J-K flip- flops. Describe the operation of an IC latch. Interpret flip-flop truth tables. Determine whether flip-flop circuits are functioning properly.
