EE200(class 3-2) Prof. M.M. Dawoud 19 EE200 DIGITAL LOGIC CIRCUIT DESIGN Class Notes CLASS 3-2 The material covered in this class will be as follows: Binary logic Switching circuits Binary signals Basic logic gates Binary Logic: Binary logic deals with variables e.g. x, y, z, A, B, C, … etc., that take on two discrete values (e.g. 1 & 0, True & False, … etc.) and logic operations. There are three basic logic operations: 1. AND Æ . xy z = Æ reads xANDyi squa ltoz and it means that 1 z = if and only if ; otherwise 0 z = . 2. OR Æ xy z + = Æ reads x OR y isqual to z and it means that 1 z = if 1 x = or if 1 y = or if both 1 x = and 1 y = . If both 0 xand y = then 0 z = . 3. NOT Æ () xz o r x z == Æ reads "" not x isequal to z meaning that z is what x is not.
