What are the advantages and disadvantages of multiplexing?
The advantage of multiplexing is that we can transmit a large number of signals to a single medium. This channel can be a physical medium like a coaxial, metallic conductor or a wireless link and will have to handle multiple signals at a time. Thus the cost of transmission can be reduced.

What are the disadvantages of using a repeater?
The disadvantage of repeater is that they reduce the performance of wireless LAN. A repeater must receive and retransmit each frame on the same radio channel, which doubles the amount of traffic needed for the network. Other than that, the problem of receiving duplicate data will happen when using multiple repeaters.
Why is crosstalk so difficult to interpret?
Answer 3: Crosstalks can occur when one signal during transmission mixes with some other signal and pick that up thereby disrupting the original message. Answer 4: When a signal moves through any medium, at the end of the medium it has a tendency
Why does noise affect the efficiency of radio frequency amplifiers?
It causes the efficiency of radio frequency amplifier to suffer because it will require the amplifiers to be linear in order to suit the different variations of the amplitudes.
Why is optical network nonblocking?
It is always desirable for an optical network to be nonblocking as blocked data will be lost due to lack of optical buffer. A network is said to be nonblocking for multicast assignments, if for any legitimate multicast connection requests from a source node to a set of destination nodes, it is always possible to provide connection path through the network to satisfy the connection request without any disturbance to the existing connections. If the path selection follows a routing algorithm to maintain nonblocking connecting capability, the network is said to be wide-sense nonblocking. In this paper, we study about wide-sense nonblocking multicast communication in wavelength reusable multi-carrier distributed (WRMD) wavelength division multiplexing (WDM) linear array, unidirectional ring and bidirectional ring networks. Also, for each type of network, the necessary and sufficient conditions on the minimum number of wavelengths required to be wide-sense nonblocking for multicast communication is derived.

What are the input bits of a 4x1 multiplexer?
The 4X1 multiplexer comprises 4-input bits, 1- output bit, and 2- control bits. The four input bits are namely 0, D1, D2, and D3, respectively; only one of the input bits is transmitted to the output. The o/p ‘q’ depends on the value of control input AB. The control bit AB decides which of the i/p data bit should transmit the output. The following figure shows the 4X1 multiplexer circuit diagram using AND gates. For example, when the control bits AB =00, then the higher AND gates are allowed while remaining AND gates are restricted. Thus, data input D0 is transmitted to the output ‘q”
How many inputs does a demultiplexer have?
The demultiplexer is also called a data distributor as it requires one input, 3 selected lines, and 8 outputs. De-multiplexer takes one single input data line and then switches it to any one of the output lines. The 1-to-8 demultiplexer circuit diagram is shown below; it uses 8 AND gates for achieving the operation.
What is the function of a demultiplexer?
The function of a demultiplexer is to inverse the function of the multiplexer. The shortcut forms of the multiplexer and demultiplexers are mux and demux. Some multiplexers perform both multiplexing and demultiplexing operations.

In analog applications, multiplexers are made up of relays and transistor switches, whereas in digital applications, the multiplexers are built from standard logic gates. When the multiplexer is used for digital applications, it is called a digital multiplexer.
How to determine if a multiplexer is a digital or analog?
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.
What are the advantages of multiplexing immunoassays?
The possible advantages of multiplexing are as follows: + More data points/unit sample. + Reduced cost/data point.
Why is multiplex assay so complex?
The shear complexity of multiplex assays means that they can take considerably longer to develop than singleplex assays, and it is for this reason that researchers regularly turn to external providers rather than developing such assays in house. This in turn limits the possibilities of meeting specific in-house analytical challenges for specific analyte combinations.

Advantages of platforms at bus stops. Is less stressful. Travelling by bus is cheaper than owning and operating a car. Reduces pollution and road congestion – the more people who travel by bus, the fewer cars on the road. You do not need to look for a place to park your card.
How long does multiplex if take?
Multiplex IF uses antibodies labeled with fluorophores to simultaneously detect multiple markers. Depending on the protocol, this can take from 2-20 hours. Standard IF microscopes typically allow whole slide visualization of 4-5 markers in a single round of staining. In contrast, multispectral microscopes are used to analyze up to 8 markers within distinct (0.66mm 2) regions of interest (ROI) that can subsequently be tiled. Emerging studies suggest that a cyclic staining approach to multiplex IF may allow for detection of 30-60 markers 3,4,5. A major advantage of multiplex IF is that the large linear dynamic range of most fluorophores allows for quantitation of marker intensity. However, fluorophores must be chosen carefully to prevent bleed-through and, where tyramide signal amplification (TSA) is used to boost signal intensity, additional checks are required to rule out potential blocking with TSA reagents.
How many markers can you see in a MICSSS?
MICSSS is similar to traditional chromogenic IHC but uses iterative cycles to visualize up to 10 markers on a whole slide 2. Detecting one marker at a time eliminates the risk of steric hindrance or bleed-through that can compromise results. However, throughput is limited (each cycle takes 1-2 days to complete) and merging individual MICSSS images ...
Why is tissue based mass spectrometry not used?
Because tissue-based mass spectrometry avoids the use of fluorophores, the risk of signal fading, spectral overlap or autofluorescence is eliminated . Counterbalancing these advantages, the main drawbacks of tissue-based mass spectrometry are that instrumentation is extremely costly and extensive training is required.
