Logic Blocks Circuit Symbols

Circuit symbols for logic / digital building blocks found within many circuits: AND, NAND, OR, NOR, exclusive OR, etc . . .

Ciircuits, Diagrams & Symbols Includes:
Circuit symbols overview     Resistors     Capacitors     Inductors, coils, chokes & transformers     Diodes     Bipolar transistors     Field effect transistors     Wires, switches & connectors     Analogue & functional circuit blocks     Logic    

There is a vareity of different symbols for logic elements within a circuit. NAND, NOR and AND and OR are the most common circuit symbols, but oters are also used.

The circuit symbols are based on those that appear to be most widely used.
