It involves the design, construction, and maintenance of communication systems,such as telephone networks, data networks, and satellite communication systems.Telecommunications engineers are responsible for ensuring that communication systems are reliable, efficient, and secure. They must have a strong understanding of the principles of communication theory, as well as the latest technologies used in the field.Telecommunications engineering is a rapidly evolving field, with new technologies being developed all the time. As a result, telecommunications engineers must beconstantly learning and adapting to new technologies.Telecommunications engineering is a challenging and rewarding field. It offers the opportunity to work on cutting-edge technologies and to make a real difference in the world.中文回答：电信工程是电气工程的一个分支，它涉及远距离的信息传输。

1."In most cases, these signals originate as sensory data from the real world: seismic vibrations visual images, sound waves, etc. DSP isthe mathematics, the algorithms, and the techniques used to manipulate these signals after they have been converted into a digital form." 在大多数情况下，这些信号来源于人对真实世界的感觉，比如地震的震动，视觉图像，声音波形等。

数字信号处理是一种数学工具，是一种用来处理那些将上述信号转换成数字形式后的信号的算法和技术。

2.Fourier’s representation of functionsas a superposition of sines and cosines has become Ubiquitous for both the analytic and numerical solution of differential equations and for the analysis and treatment of communication signals 函数的傅里叶表示，即将函数表示成正弦和余弦信号的叠加，这种方法已经广泛用于微分方程的解析法和数值法求解过程以及通信信号的分析和处理。

3.If f (t ) is a nonperiodic signal, the summation of the periodic functions ,such as sine and cosine, does not accurately represent the signal. You could artificially extend the signal to make it periodic but it would require additional continuity at the end points . 如果f(t)是非周期信号，那么用周期函数例如正弦和余弦的和，并不能精确的表示该信号f(t)。
