Now let us understand about both multiplexers and demultiplexers along with their applications and block diagrams.
Multiplexer means many into one. A multiplexer is a circuit used to select and route any one of the several input signals to a single output. A simple example of an non-electronic circuit of a multiplexer is a single pole multi-position switch. Multi-position switches are widely used in many electronics circuits. However, circuits that operate at h...
Demultiplexer means one to many. A demultiplexer is a circuit with one input and many outputs. By applying control signal, we can steer any input to the output. Few types of demultiplexer are 1-to 2, 1-to-4, 1-to-8 and 1-to 16 demultiplexer. Following figure illustrate the general idea of a demultiplexer with 1 input signal, m control signals, and ...
1. Input and Output
Multiplexers have multiple input lines, each carrying a potential data signal. These input lines are selected by control signals, often referred to as select lines. The chosen input is then transmitted to a single output line. In contrast, Demultiplexersoperate in reverse. They have a single input line and multiple output lines. The input data is directed to a specific output line based on the control signals, effectively distributing the data across multiple channels.
2. Data Flow
A Multiplexer exhibits a many-to-one data flow, consolidating multiple input data streams into a single output channel. This consolidation is achieved through the selection process governed by the control signals. And, Demultiplexeroperates in the opposite direction, characterized by a one-to-many data flow. It distributes a single input signal across multiple output lines, with the specific output channel determined by the control signals.
3. Function
Multiplexer acts as a data selector. It chooses one input signal from multiple inputs based on the control signals applied to its select lines. Essentially, it combines several data streams into a single output. While, a Demultiplexerperforms the opposite function. It takes a single input signal and distributes it to multiple output lines, selecting the specific output channel based on the control signals. In essence, it acts as a data distributor.
An introductory tutorial on Multiplexer and Demultiplexer. Learn the basics of Multiplexer, understand a basic 4-to-1 Multiplexer, applications of Multiplexer, Demultiplexer, a basic 1-to-4 Demultiplexer, applications of Demultiplexer.
Sep 3, 2024 · A Multiplexer (or MUX), sometimes referred to as a data selector, operates by choosing among multiple analog or digital input signals and directing the chosen input to a single output line. This selection process is governed by a separate collection of digital inputs termed select lines.
Applications. Multiplexers are part of computer systems to select data from a specific source, be it a memory chip or a hardware peripheral. A computer uses multiplexers to control the data and address buses, allowing the processor to select data from multiple data sources.
Oct 26, 2023 · Multiplexers are devices that select and forward one input signal from multiple inputs based on control signals. They are used in data routing, hardware implementation, memory management and more. Learn about their design, integration and evolution in digital electronics and communication.
