What is a multiplexer?a)It is a type of decoder which decodes several ...
Explanation:
A multiplexer is a device that combines multiple signals into one output signal. It is also known as a data selector, as it selects one of several input signals and forwards the selected signal to the output. The number of input signals can be two or more, and the selection of the input signal can be done through a control signal.
Working Principle:
The working principle of a multiplexer is based on the Boolean expression. A multiplexer has n input lines and one output line. The control signal selects which input to send to the output. The control signal is converted into a binary number, which is used to select one of the input lines.
Types of Multiplexers:
There are different types of multiplexers, including:
1. 2:1 Multiplexer: It has two input lines and one output line.
2. 4:1 Multiplexer: It has four input lines and one output line.
3. 8:1 Multiplexer: It has eight input lines and one output line.
Applications:
Multiplexers are used in various applications, including:
1. Communication systems: Multiplexers are used in communication systems to combine multiple signals into a single output signal.
2. Computer memory: Multiplexers are used in computer memory to select a particular memory cell.
3. Data transmission: Multiplexers are used in data transmission systems to select a particular data stream.
4. Digital circuit design: Multiplexers are used in digital circuit design to select an input signal based on a control signal.
Conclusion:
In conclusion, a multiplexer is a device that combines multiple signals into one output signal. It is widely used in various applications, including communication systems, computer memory, data transmission, and digital circuit design.
