Entire circuits with Gates can also be also be burnt into
PLDs, FPGAs and CPLDs just like you burn your CDROM. Gates can
also be implemented in assembly language which a
microcontroller like 8051 will understand and execute.
Hardware gate circuit will operate in real time, propagation
delay of nano seconds will be there due to parasitic gate
capacitance or FET switching times. Software Gates using
microcontroller and code will depend on both propagation delay
of semiconductor, CPU clock speed and BUS width.
This gate ANDs the two inputs A and B, The Output is high
only if A AND B both are high. There may be a AND gate with
many inputs, only if all inputs are high the output will be
The Gate is a digital component that is used to compute an
output for certain inputs, the inputs and outputs have two
states high-1 and low- 0. Let us assume high is 5V and low is 0V
(like in CMOS). On a high level the LED will light up and on a
low level the LED is off. Now let us see what Logic means.
