Digital Circuit Fundamentals 1 Unit 1 – Circuit Board Introduction
Exercise 1 – Component Location and Identification
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to locate the major circuit blocks on the
circuit board. You will verify your results by correctly identifying circuits and their major
components.
DISCUSSION
- The trainer provides circuits which count, add, compare, and shift digital signals. The trainer
is organized into five circuit block units. Each unit may use more than one of the ICs as
active circuit elements. - Monolithic ceramic decoupling capacitors prevent instability and are located near their
respective devices. - Circuit blocks are multifunctional. Two-post connectors are used to select and/or connect
circuit blocks. - Test points and LEDs are provided for voltage level verification.
- Titles of each circuit block are indicative of their basic function. The symbols within the IC
denote signal function.
