Performance Of Multiplexing Multiplexer

- Jul 12, 2017-

Multiplexer (or abbreviated MUX) is simple to design a signal chain, right? After all, a device simply puts multiple signals into a data converter.

In fact, the multiplexer can significantly affect the performance of the signal chain in various ways. For example, the conduction capacity may cause crosstalk between channels. The signal and temperature-dependent variations of the conduction resistance may cause signal distortion. The capacitance and resistor of multiplexer can limit the signal bandwidth. When the multiplexer switches the channel and affects the stable time at the output, Multiplexers the charge injection may cause the transient error.

In order to optimize signal chain performance, it is important to understand the many other ways in which these examples and multiplexer can affect the signal, especially since multiplexer is optimized for different performance characteristics and applications. For the example circuit containing the multiplexer, Multiplexers the output is connected to the inverse Operation Amplifier (op amp).

Multiplexer is a device capable of receiving multiple input signals and synthesizing a single output signal according to the recoverable mode of each input signal. Multiplexers Multiplexer is an integrated system that usually contains a certain number of data inputs and has a single output.

Principle Multiplexer 1. In meaning electronics, multiplexer (multiplexer or MUX) can select a signal from multiple analog or digital input signals and forward it, outputting different selected signals to the same output line

The supplier of multiplexer is an integrated system that usually contains a certain number of data inputs and N address inputs (which select a data input in binary form). The multiplexer has a separate output that is the same as the selected data input value. Multiplexing techniques may follow one of the following principles, Multiplexers such as TDM, FDM, CDM, or WDM. Reuse technology is also applied to software operations, such as the simultaneous transmission of multithreaded information to a device or program.

In analog carrier communication systems, the frequency division multiplexing method is usually used to improve the transmission capacity of the system, to make full use of the bandwidth resources of the cable, that is to transmit several channel signals simultaneously in the same cable, and the receiving end can filter out each channel signal according to the different carrier frequencies. Similarly, in the optical fiber communication system, the frequency division multiplexing method can be used to improve the transmission capacity of the system, and the signal optical carrier is separated by a solution multiplexer (equivalent optical bandpass filter) at the receiving end. Because the frequency difference of the signal is quite large in the frequency domain of the light, the wavelength is generally used to define the difference of frequency, which is called Wave Division multiplexing. The WDM technology is to make full use of the huge bandwidth resources brought by the low loss zone of Single-mode fiber, according to the frequency (or wavelength) of each letter Daoguanpo, the Low loss window of the optical fiber can be divided into several channels, the wave is used as the carrier of the signal, and a multiplexer (a wave collector) in the transmitter is combined to transmit the signal light carrier with different specified wavelengths into a fiber. At the receiving end, the multiplexing method is separated by a multiplexer (a wave splitter) which carries the different wavelengths of the optical carrier. Multiplexers Because the optical carrier signals of different wavelengths can be regarded as independent (without considering the nonlinearity of the optical fiber), multiplexing transmission of multi-channel optical signals can be realized in one optical fiber. Two-way transmission can be achieved by arranging two signals at different wavelengths. Depending on the multiplexer, the number of wavelengths that can be reused varies from 2 to dozens of, and the general commercialization is 8-wavelength and 16-wavelength systems, depending on the length of time allowed for the light carrier wave, and gives its system composition.
