Decoders Tutorial

Decoding is the recovery of previously encoded data.

In the diagram, the push buttons ENCODE decimal to binary.

The gates DECODE the binary and turn on the decimal indicators.

Gate 1 recognises when the least significant bit is high and the adjacent bit is low.

The inverter turns the low into a high, so that gate 1 has two high inputs.
