SUBCOURSE 327, FREQUENCY SYNTHESIS
INTRODUCTION
Radio communication is successful only when the communicators share the
frequency spectrum and when they respect the frequency channel of every other
communicator. Both of these operating requirements are best served by the use of
As the name implies, a frequency synthesizer develops secondary frequencies from
primary sources.
These secondary frequencies may be developed through selecting
harmonics, heterodyning harmonics, or heterodyning two stable frequencies to create
a third. Moreover, the stability of the synthesized frequencies will be no better
than the stability of the source frequencies.
Since many radio transmitters and receivers used in operating nets contain
compatible frequency synthesizers, all communicators should understand their
operation.
This subcourse gives you the fundamental concepts of frequency
synthesis with a block diagram analysis of different types of synthesizers.
This subcourse consists of two lessons and an examination, as follows:
Lesson 1.
Introduction to Frequency Synthesis
Lesson 2.
Classes of Synthesizers
Examination
Credit Hours: 5
You are urged to finish this subcourse without delay; however, there is no
specific limitation on the time you may spend on any lesson or the examination.
