2-Bit Binary Decoder
A simple application of a digital electronics combination circuit is shown below.
It is a 2 bit binary decoder implemented with inverters and NOR gates.
Input consists of 2 binary bits A and B. There are 4 outputs, one
for each of the 4 possible combinations of AB(00 01 10 11). The states
of A and B can be changed by clicking on the rectangular areas marked click.
Blue corresponds to LOW and red to HI.
In applet below the same circuit is implemented with inverters and NAND
gates. In this case the output is normally HI and goes LO when activated.
