electricians and technicians in instrumentation and electronics as well as for
the multi-craft training needs of process and manufacturing facilities.

**Associated Course Lessons**

**Lesson Title**: Lesson 1- Binary Logic Circuits Lesson

**Prerequisite**: This lesson is designed for participants familiar with
AC/DC theory, electrical safety, and electrical print reading. A basic understanding
of logic gates is also required.

**Lesson Description**: This lesson explains and demonstrates binary logic
signals and the use of logic gates in integrated circuits. The lesson also describes
Boolean expressions, truth tables, and Karnaugh mapping in relation to the logic
of complex circuits. These topics are directly applied to troubleshooting digital
circuits.

**Lesson Outcome**: Upon completion of this lesson, participants will be
able to identify voltages of digital components; identify leading and trailing
edges of a digital signal; interpret pin connection diagrams and wiring diagrams;
state the function of a pin on an IC chip when provided with a pin connection
diagram or a wiring diagram; properly use a logic probe, logic clip, logic monitor,
and logic pulser to test the operation of an IC chip; test the operation of
a circuit and determine if it is functioning properly; interpret and develop
related Boolean expressions and truth tables; and simplify a two-variable Boolean
expression using Karnaugh mapping.

**Lesson Title: Lesson 2**- Codes, Encoders, Decoders, and Flip-Flops

**Lesson Prerequisite**: 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.

**Lesson 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.

**Lesson Outcome**: Upon completion of this lesson, participants will be
able to 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; and determine whether flip-flop circuits are functioning
properly.

**Lesson Title: Lesson 3-** Counters and Shift Registers

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

**Lesson Description**: This lesson discusses the principles of counters
and their various applications. The lesson also explains the principles and
features of shift registers, emphasizing serial load shift registers, parallel
load shift registers, and universal shift registers. Troubleshooting counters
and shift registers is also addressed.

**Lesson Outcome:** Upon completion of this lesson, participants will be
able to determine binary outputs and the limits for counters; understand how
input pulses affect the counter's output; identify synchronous and asynchronous
counters; define ripple counters, up/down counters, self-stopping counters and
frequency dividers; use count sequence tables in troubleshooting counters; understand
the basic shifting concept; state the difference between serial load shift registers
and parallel load shift registers; identify universal shift registers; and troubleshoot
counters and shift registers.

**Lesson Title: Lesson 4**- Data Transmission, Conversion, and Storage

**Lesson Prerequisite:** 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.

**Lesson 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.

**Lesson Outcome:** Upon completion of this lesson, participants will be
able to 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; and distinguish between ROM and RAM,
and between PROM, EPROM and EAROM.
