How do you implement a function using a decoder?

Thus, a Decoder can be used to implement a function of n variables simply by connecting the outputs of the Decoder that correspond to the minterms of a function to a multi-input OR gate. Consider the Decoder circuit shown in Figure 7 which implements two separate functions of three variables.

What is decoder and how it works?

A decoder is a circuit that changes a code into a set of signals. It is called a decoder because it does the reverse of encoding, but we will begin our study of encoders and decoders with decoders because they are simpler to design.

What is decoder with example?

A decoder is a circuit which has n inputs and 2ⁿ outputs, and outputs 1 on the wire corresponding to the binary number represented by the inputs. For example, a 2-4 decoder might be drawn like this: and its truth table (again, really four truth tables, one for each output) is: i₁. i₀.

What is decoder and its use in combinational logic implementation?

Decoder is a combinational circuit that has 'n' input lines and maximum of 2ⁿ output lines. One of these outputs will be active High based on the combination of inputs present, when the decoder is enabled. That means decoder detects a particular code.
