Introduction: Logic AND Gate
The AND gate is a logic Boolean gate that represents multiplication in basic algebra. When both input to the AND gate are forced to a logic HIGH (1) level, the output will be forced to a logic HIGH (1) level. But if either of the inputs are forced to logic LOW (0) the output will be forced to a logic LOW (0). This is the equivalent of a multiplication statement where only Boolean variables are allowed. The symbol and truth table for an AND gate can be seen here.
