英国电子工程学论文代写:数据传输错误

由于抖动的“误码率(BER)”降低,数字通信的质量受到损害,从而导致质量下降以及“差”质量。因此,评估抖动对数字通信系统的影响是必不可少的,以减少抖动并获得较低的误码率。研究表明,这些设备可能会受到抖动的负面影响;在存在抖动的情况下,通过设备的信号和时钟信号经常变化或波动。热噪声的存在会导致抖动影响时钟信号,而有限的信道带宽或时钟抖动会导致抖动对数据信号产生影响。输入,输出和时钟信号之间的时间关系是数字技术中非常关键的关键。在这种“定时”关系中的任何偏差都可能导致数据传输错误,进而被称为“抖动”。为了数字通信的目的,数据从发射机流向接收机,其中数据按照0和1的。通信的传输是通过接口或光纤或铜线来实现的。即使空气也是现代数字通信中的有效传输接口。此外,现代通信系统被设计为使得“吞吐量”最大化并且使错误最小化,并且因此可以使用比特错误率来评估这些错误。
任何输入信号引起的抖动都会导致数据恢复(CDR)电路与作为数字通信系统一部分的接收器的时钟一起中断。这种故障导致数据的时间采样很差,反过来会导致误码。换句话说,可以说抖动是接收数据错误的主要原因。

Due to the decrease in the “bit error ratio (BER)” of Jitter, the quality of digital communication is compromised thus resulting in reduced as well as “poor” quality. For this reason, evaluation of the effect of Jitter on the digital communication system is essential so as to reduce Jitter and obtain a lower bit error ratio. Research states that the devices can be negatively affected by jitter; the signal travelling through the device and the clock signal often change or fluctuate in the presence of jitter. The presence of thermal noise causes the jitter to affect the clock signal while the limited channel bandwidth or clock jitter causes the jitter to have an effect on the data signal. The timed relationship between input, output & clock signals is a highly crucial key in digital technology. Any deviation in this “timed” relationship may result in data transfer error that in turn is referred to as “jitter.” For the purpose of digital communication, the data flows from the transmitter to receiver where the data is arranged in a sequence of 0’s and 1’s. Transmission of communication occurs through interfaces made up or fiber or copper; even air acts as an effective transmission interface in modern digital communication. Additionally, the modern communication system is designed in such a way that it maximizes “throughput” and minimizes errors and thus, these errors can be evaluated with the use of the quantity of Bit Error Ratio.
The jitter that is caused by any incoming signal is responsible for breaking down the Data Recovery (CDR) circuit along with Clock of the receiver that is a part of the digital communication system. This malfunction results in poor time sampling of data which in return would cause bit errors. In other words, it can be said that Jitter acts as the primary cause for the errors in the data that is received.
