Decoders are circuits which convert a N-bit input signal into 2N 1-bit output signals. Only one of the output signals will be HIGH (1) for any given input value. If the i-th output is 1, it means that the input had a value of i
.
NOTES
- Some of the circuits in this category use components from the 1-bit Multi-input Gates category.
- Since the outputs from each circuit are 2N independent signals, I could have used 2N 1-bit output ports. I decided to use a normal 2N-bit output port. When you componentize the circuits below, the generated component will have 2N output pins, since the output port is not a bus.
