How is an encoder different from a decoder?a)The output of an encoder ...
Encoder vs Decoder:
Encoder and decoder are digital circuits that perform different functions. An encoder is a circuit that converts an active input signal into a coded output signal. In contrast, a decoder is a circuit that converts a coded input signal into an active output signal. Let's dive into the differences between the two:
Output of an Encoder:
The output of an encoder is a binary code for 1-of-N input. Here's what this means:
- An encoder has N input lines and 2^N output lines.
- When a signal is active on one of the input lines, the encoder produces a binary code on its output lines that represents the active input line.
- The binary code is typically in the form of a 1-of-N code, which means that only one of the output lines is active at a time, and the rest are inactive.
Output of a Decoder:
The output of a decoder is a binary code for N-of-1 output. Here's what this means:
- A decoder has 2^N input lines and N output lines.
- When a binary code is applied to the input lines, the decoder activates the corresponding output line.
- The binary code is typically in the form of a N-of-1 code, which means that only one of the input lines is active at a time, and the rest are inactive.
Conclusion:
In summary, an encoder converts an active input signal into a coded output signal, while a decoder converts a coded input signal into an active output signal. The key difference between the two is the type of binary code that they produce. An encoder produces a 1-of-N code, while a decoder produces a N-of-1 code.

n encoder is a combinational circuit encoding the information of 2n input lines to n output lines, thus producing the binary equivalent of the input. It performs the opposite operation of a decoder which results in 2n outputs from n inputs. Thus, an encoder different from a decoder because of the output of an encoder is a binary code for 1-of-N input.
