At this skripsi is conversed to hit the application of mathematics logic specially logic of algebra Boolean in compilation of electrics network, namely in the switching circuits and digital circuits.
Algebra Boolean represent a way of newly to think, a way of newly to explain the matters by using notations in the place of words in reaching logic conclusion.
Application of Algebra Boolean in the switching circuits is used to determine a current emiting stream of through/ passing the circuit, and alter the switching circuits in the form of symbolic and also compile the circuit in such a way that become more simple. Application in digital circuit is alter the circuit in the form of equation Boolean and determine the way of job a circuit.
Key words: Logic, Electrics network, and Circuit digital.
