ABSTRACT
Circuit diagrams in the broad sense can cover a wide range of different circuit or system representations. Block diagrams can be a very useful tool in the early stages of the design process, allowing for the general architecture of a circuit to be analysed and assessed. A circuit may be battery powered or it may take its power from an alternating current adapter, or it might be deemed desirable to allow for either option. Audio effects circuits will typically require a bypass option so that they can be switched in and out of the signal path. Laying out a circuit, whether on breadboard, stripboard, or printed circuit board, is as much an art as a science. Breadboards enable simple plug and play circuit construction.
