Circuit Symbols |
|||||||||
Circuit diagrams form the basis of all communicable electronic concepts and designs and an understanding of them is essential to gain an understanding of what they describe. They form a language of their own with it's own rules of grammar and construction. Presented here is the basic vocabulary of that language, i.e. the symbols used to represent the components |
