Digital Circuit Fundamentals 1 Unit 1 – Circuit Board Introduction
UNIT 1 – CIRCUIT BOARD INTRODUCTION
UNIT OBJECTIVE
At the completion of this unit, you will be able to identify and operate the circuit blocks on the
DIGITAL CIRCUIT FUNDAMENTALS 1 circuit board.
UNIT FUNDAMENTALS
The DIGITAL CIRCUIT FUNDAMENTALS 1 circuit board consists of 5 training circuit
blocks.
A general purpose circuit block consists of a 5V regulator, a square wave CLOCK generator, a
PULSE GENERATOR circuit, and an INPUT SIGNALS generating set of toggle switches.
A voltage regulator converts the system's 15 Vdc power supply to 5 Vdc, which is required by
the integrated circuits (ICs) on the circuit board.
Power supply voltages are hardwired to all ICs on the circuit board.
