It is a result obtained when the logic values (truth T), or false (F) “I” or “0” of the input variables are substituted into the expression for a logic function. In general, logic gate may have n-inputs but usually only one output. If we have n-inputs; then there will be 2 3ossible combination of the …
It is a table that shows all possible combination of the input condition and the resulting condition of the output.
A logic gate is an electronic circuit in which the logic level of the output signal depends on the logic state of one or several input signals. It is the basic building block of most digital electronic circuits. The fig 15.1 below shows a general block diagram of a logic gate. The alphabets A, B …
