Summary
● Schematic symbols are symbols used to represent electrical and electronic schematic diagrams.
● Schematic diagrams are used to show how a circuit is connected.
● Reference designators identify components in a schematic diagram.
● A block diagram represents how the component blocks of a circuit are connected.
● A schematic diagram shows how the components are connected in a circuit.
● Analog schematic diagrams show how the discrete analog components are connected.
● Digital schematic diagrams use integrated circuits and have many common signals throughout the schematic; therefore, they use common signals rather than draw every line.
● A good schematic diagram should show the entire circuit in as few drawings as possible.
● Breadboarding allows circuits to be assembled and altered quickly.
● Breadboarding uses discrete components to build a circuit.
● Virtual breadboarding uses the computer to build and test the circuit without any analog components.
