Multiplexers & Demultiplexers
Multiplexers and demultiplexers allow digital information from multiple sources to be routed through a single line. A multiplexer has multiple data inputs, select lines to choose an input, and a single output. A demultiplexer has a single input, select lines to choose an output, and multiple outputs. Bigger multiplexers and demultiplexers can be built by cascading smaller ones. Multiplexers can implement logic functions by using the select lines as variables and routing the input lines to the output.
Multiplexer and DeMultiplexer
A multiplexer has multiple inputs and a single output line, using select lines to determine which input is connected to the output. It is used to increase the amount of data that can be sent over a network. A demultiplexer is the reverse, with one input and multiple output lines, using select lines to send a signal to one of the output lines. Both are used in communication systems, computer memory, and other applications to efficiently transmit data or connect parts of a system.
Multiplexers
A multiplexer is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. It has multiple data inputs, a single output, and select lines that determine which input is directed to the output. A demultiplexer performs the opposite function, taking a single input and distributing it to one of multiple outputs based on the select lines. Multiplexers and demultiplexers come in various configurations depending on the number of inputs and outputs, such as 2:1, 4:1, 16:1 or 32:1. They are basic building blocks used in digital systems and communication networks to efficiently route signals.
Demultiplexer
A demultiplexer is a device that takes a signal containing multiple data streams and reconstructs the original separate streams. It works in reverse of a multiplexer, which combines multiple streams into one signal. Demultiplexers come in various types depending on the number of select lines, which determine how many output streams they can separate the combined signal into, from 1-to-2 up to 1-to-16. Common applications of demultiplexers include communication systems and converting serial to parallel signals.
multiplexers and demultiplexers
This document discusses multiplexers and demultiplexers. It defines them as devices that allow digital information from several sources to be routed onto a single line (multiplexers) or distributed to multiple output lines (demultiplexers). The key properties of multiplexers and demultiplexers are described, including the relationship between the number of inputs, outputs, and selection lines. Examples of implementing multiplexers and demultiplexers using logic gates are provided.
Multiplexers
A multiplexer (MUX) is a digital switch that selects one of several input lines and outputs the selected input to a single output line. It uses select lines to determine which input is connected to the output. A typical application is connecting multiple audio/video sources like an MP3 player, laptop, satellite receiver, or cable TV to a single output destination like a home theater system. The document demonstrates a 4-to-1 MUX that uses two select lines A and B to choose one of four data inputs D0, D1, D2, or D3 and output it to line Y.

Encoder and decoder
An encoder is a circuit that takes a digital input and converts it to a binary code output. It performs the inverse operation of a decoder. There are different types of encoders like priority encoders, decimal to binary coded decimal encoders, and hexadecimal to binary encoders. A priority encoder gives priority to certain input lines such that if multiple lines are high, the output corresponds to the highest priority line. A decimal to BCD encoder takes a 10-bit decimal input and produces a 4-bit binary coded decimal output corresponding to each decimal value. Standard encoder integrated circuits like the 74HC147 implement common encoder functions.

The document explains about the concepts of sequential circuits in Digital electronics.
This will be helpful for the beginners in VLSI and electronics students.
Modulo n counter
A modulus-n counter is a sequential logic device that counts through a predetermined sequence of states when triggered by a clock signal. The number of states it cycles through before returning to the initial state is called its modulus. For example, a 2-bit counter with states 00, 01, 10, 11 has a modulus of 4. The maximum modulus of an n-bit counter is 2^n. Modulus counters are used in applications like frequency counters, digital clocks, time measurement, and more.
encoder and decoder in digital electronics
In digital electronics, a decoder can take the form of a multiple-input, multiple-output logic circuit that converts coded inputs into coded outputs, where the input and output codes are different e.g. n-to-2n , binary-coded decimal decoders. Decoding is necessary in applications such as data multiplexing, 7 segment display and memory address decoding.
An encoder is a device, circuit, transducer, software program, algorithm or person that converts information from one format or code to another. The purpose of encoder is standardization, speed, secrecy, security, or saving space by shrinking size. Encoders are combinational logic circuits and they are exactly opposite of decoders. They accept one or more inputs and generate a multibit output code.

Basic mathematics of MIMO technology.pptx
The document discusses the basic mathematics behind MIMO (Multiple Input Multiple Output) technology used in wireless communications. It contains the following key points:
1) MIMO systems use multiple antennas at both the transmitter and receiver to enhance performance. This allows for transmitting and receiving multiple data streams simultaneously.
2) There are two main MIMO modes - spatial multiplexing provides throughput/capacity gains by transmitting different data symbols from each transmitter, while space-time block coding provides diversity gains through redundant transmission to improve reliability.
3) The MIMO system can be modeled by a channel matrix relating the transmitted and received signals, where each element represents fading between an antenna pair. Techniques like zero-forcing equalization are used

Combinational circuit
An integrated circuit is a small chip of silicon that contains multiple transistors. Decoders and encoders are types of combinational logic circuits. A decoder accepts an input and uses it to activate one of its outputs, while an encoder performs the inverse by activating its outputs based on active inputs. Decoders and multiplexers are similar in that they select an output from multiple inputs, but decoders have multiple outputs while multiplexers have a single output. Multiplexers can be cascaded to increase the number of inputs selected from.
MULTIPLEXER Circuit in Digital system/electronics/logic
MULTIPLEXER Circuit is a data selector. It is a device that selects between several analog or digital input signals and forwards the selected input to a single output line.

COMPUTER ORGANIZATION -Multiplexer,Demultiplexer, Encoder
This document discusses multiplexers, demultiplexers, and digital encoders. It provides the following information:
- Multiplexers are digital circuits that select one of several input signals and output the selected signal. Demultiplexers perform the reverse operation.
- Multiplexers and demultiplexers come in variations depending on the number of input/output channels such as 2:1, 4:1, 16:1, etc. Their operation is illustrated using logic gates.
- Digital encoders convert binary input lines into an equivalent binary code output. Priority encoders were developed to solve issues with standard encoders generating incorrect outputs when multiple inputs are high.
