What is the use of select lines in multiplexer?
select lines, which are used to select which input line to send to the output. A multiplexer makes it possible for several input signals to share one device or resource, for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal.
What is a multiplexer & State its uses in practical applications?
A multiplexer is used to convert several analog or digital signals into a single o/p signal through different control lines. These control lines can be determined by using this formula like 2n=r where ‘r’ is the no of i/p signals & ‘n’ is the no of required control lines.
Why a multiplexer is called a data selector?
In digital electronics, multiplexers are also known as data selectors because they can “select” each input line, are constructed from individual Analogue Switches encased in a single IC package as opposed to the “mechanical” type selectors such as normal conventional switches and relays.
What are the applications of multiplexer?
Applications of Multiplexer Multiplexer allow the process of transmitting different type of data such as audio, video at the same time using a single transmission line. Telephone Network – In telephone network, multiple audio signals are integrated on a single line for transmission with the help of multiplexers.
How does a multiplexer work in an integrated circuit?
Further, multiplexers integrated circuits are having ENABLE input, which has to to be activated to perform the multiplexer operation. In multiplexer depending upon select lines the binary data present on inputs is passed to the output line.
How many control lines does a multiplexer have?
This multiplexer has active LOW ENABLE input and active LOW output. 1. The number of control lines for a 8 – to – 1 multiplexer is 2. IC 74LS153 is a ______.
Which is better a multiplexer or a gate?
In most cases, lowest component count turns out to the lowest cost solution as well. If you need a 16–1 multiplexer, it is probably better than 4 x 4–1 multiplexers and a few gates, it will have better quality and reliability and most likely better cost.
When does NAND give out a high voltage?
NAND gives out a high voltage output only when both inputs are low. NOR gives out a high voltage output when at least one input is low. XOR gives out a high voltage output when only one input is high. XNOR gives out a high voltage output only when both inputs are the same.
