• The objective of this lesson is to show you how beneficial this is, by having you trace the DC Power, Signal, and Control lines in the circuits provided.
• In order to demonstrate how this works,
we will use a simple superhet receiver circuit as an example.
• Print out the following page, which is the simple superhet circuit, and color the DC power and signal lines as shown on the subsequent pages.
