As you learn to read and draw schematic diagrams, you might get discouraged by the complexities that arise. You might think, “Oh sure, anyone can learn to read schematics of simple circuits, like those that have a transistor or two, a few capacitors, and a few resistors. But it must be impossible to decipher more complicated schematics without decades of experience.” That’s not true! You’ll have to put some effort into the learning process, but you can always break a large, complicated system down into smaller, simpler circuits.
Identifying the building blocks
Even a circuit whose diagram looks overwhelming at first glance comprises multiple building blocks interconnected in an orderly, logical way. This principle never fails! ...
