The truth table for an AND gate is shown to the right. As can be seen from the truth table, the only time the output function (fisali is when both inputs (a,b) are 1s. A1 in digital logic generally represents a high' or +5 volt signal. To experiment with an AND gate, click on the DEMO' button above. Click on the dip switches to toggle the inputs (a,b) between values of 1 (high) ...
