Binary Decoder - how it works
A decoder activates only one of several outputs, depending on the combination of binary signals at the inputs.
Circuit design: 2-to-4 decoder
A 2-to-4-bit decoder has two inputs and four outputs. Only one output is active at any given time.
Step 1: Truth table
Step 2: Creating a logical equation for each output
Step 3: Develop a circuit from the logic equation
