what are the applications of decoder and demultiplexer?
A decoder is a combinational logic circuit that has n input lines and 2^n output lines, where only one output line is active at a time. It is used to convert a binary code into a one-hot output. On the other hand, a demultiplexer is a combinational logic circuit that has one input line and 2^n output lines, where the input line is routed to one of the output lines based on the select lines. It is used to route a single input signal to multiple output lines based on the select lines.
The symbol for a decoder has n input lines and 2^n output lines, represented by a rectangle with n input lines and 2^n output lines coming out. The symbol for a demultiplexer has one input line and 2^n output lines, represented by a rectangle with one input line and 2^n output lines coming out, and one or more select lines coming in.
Both a decoder and a demultiplexer are combinational logic circuits, meaning their outputs are determined solely by their current inputs. They both have multiple output lines and are used in digital systems to route signals. Additionally, they can both be built using basic logic gates such as AND, OR, and NOT gates.
A decoder is commonly used in applications where multiple inputs need to be decoded into one output, such as in memory addressing and data selection. A demultiplexer is often used in applications where a single input needs to be routed to multiple outputs, such as in data transmission and signal routing.
Technically, yes. A decoder can be used as a demultiplexer by connecting the input line to one of the select lines and using the remaining select lines as the output lines. Similarly, a demultiplexer can be used as a decoder by connecting the input line to one of the output lines and using the remaining output lines as the select lines. However, it is not recommended to use them interchangeably as their designs and functionalities are optimized for their specific purposes.
