To simplify the discussion, we use decimal numbers to illustrate this point. In some filter design problems, a primary objective may be to control some aspect of the time response such as the impulse response or the step response. 注：常用的主语有以下名词：aim, task, duty, goal, work, job, role, problem, mistake etc. 上海海事大学信息工程学院 常用写作句型 毫无疑问…… There is no doubt that…… There is no question that…… Without doubt (question), …… Beyond doubt (question), …… No (out of ) doubt, …… 句子翻译练习 根据上面的实验结果，毫无疑问，A教授提出的新算法性能更好。 显然，在这种情况下，信号波形能无失真地被传输。 上海海事大学信息工程学院 句子翻译练习 This is a microprocessor controlled communication system. Transistors are temperature sensitive. An extremely low temperatures, near absolute zero, some conductors lose the last vestige（一点点） of resistance, a phenomenon referred as superconductivity. One of the principal applications of the diode is in the production of a DC voltage from an AC supply, a process called rectification(整流). The ratio of charge to potential is called the capacitance(电容) of the body. 上海海事大学信息工程学院 Words in listening material approaching?–?v.?moving in a path leading to a place or thing artificial intelligence?– n. the development of computers to perform intell
