LOGIC GATES

NOT • There are three main logic gates. • NOT: • If 0 is input then it outputs 1; • If 1 is input then it outputs 0. Input Output INPUT OUTPUT

AND • The AND gate outputs 1 only if both inputs are 1. Input A Input B Output INPUT A OUTPUT INPUT B

OR • The OR gate outputs 1 if either of the inputs is 1. Input A Input B Output INPUT A OUTPUT INPUT B

• http: //logic. ly/demo • Make sure that you label each diagram correctly with the different inputs and outputs completing the true tables for each diagram.

Logic Circuits • We can now complete the output by looking at input C. As this is an NOT gate, the output is the opposite of the input INPUT A C INPUT B INPUT A INPUT B 1 1 1 0 0 1 1 1 INPUT C Q OUTPUT Q
