What does high input means in decoder?

In the context of a decoder, "high input" typically refers to an input signal that is at a logic high level, representing a binary value of '1'. When the decoder receives a high input on one of its lines, it activates the corresponding output line, effectively translating the binary input into a specific output. This is crucial for applications like digital circuits where specific signals need to be routed based on the input conditions. High inputs are essential for determining which output should be activated in a multi-line system.
