LESSON 1
INTRODUCTION TO TIMERS
SCOPE...........................
Introduction to timers; basic
operating principles of timing
systems; block diagram and
function of each element in a
basic timing system; analysis of
timing waveforms.
TEXT ASSIGNMENT.................
Pages 1 through 23
MATERIALS REQUIRED..............
None
SUGGESTIONS.....................
Do not become confused when you
see the term "pulse recurrence
time." It has the same meaning as
pulse repetition period.
LESSON OBJECTIVES
When you have completed this lesson, you will be able to:
a. Derive the frequency composition of basic nonsinusoidal
waveforms.
b. Determine the circuit bandwidth that is needed to pass
waveforms without distortion.
c. Recognize poor high and low frequency response by analyzing
the input and output waveforms for a circuit.
d. Identify and describe the waveshaping actions of various
waveshaping circuits.
e. Analyze the operation of a basic timing system to determine
the shapes and frequencies of the output waveforms.
