解码器:
该解码器是一个组合逻辑电路,其目的是对提供给它的数据进行解码。它由 n 条输入线和 2*n 条输出线组成。对于每一种可能的输入条件,都有不同的输出信号,根据输入,只有一个输出信号会产生逻辑。因此,这个 n 到 2n 解码器也称为最小项生成器,其中每个输出仅在特定输入上产生结果。

解复用器:
这个解复用器与解码器有点相似,但它也包含选择线。它用于通过多条输出线发送单个输入。它接受来自一个输入信号的数据,并通过提供的输出线数进行传输。它包含数据输入线、选择线和输出线。

解码器和解复用器的区别:

S.No. Comparison Decoder Demultiplexer
1. Basic These are Logic circuit which decodes an encrypted input stream from one to another format. It is a Combination circuit which routes a single input signal to one of several output signals.
2. Input/Output n number of input lines and 2n number of output lines. n number of select lines and 2n number of output lines.
3. Inverse of Encoder. Multiplexer.
4. Application In Detection of bits, data encoding. In Distribution of the data, switching.
5. Use It is used for changing the format of the instruction in the machine specific language. It is used as a routing device to route the data coming from one signal into multiple signals.
6. Select Lines Not contains. Contains.
7. Implementation Majorly implemented in the networking application. Employed in data-intensive applications where data need to be changed into another form.
