摘要
(t)函数是信号与系统中一个极为重要的一个函数,广泛应用于通信系统中[1]。人们对此的定义,是因为理论的需要,实际不存在于实际工程中。在目前关于函数的具体定义中,就产生了一个巨大的模糊点,从而引发了本文的思考。模糊点在于冲激函数的宽度是如何定义的。针对于模糊点,做出了如下的推导和证明,并针对模糊点做出了研究验证,最后得出了一个合理的说明。
Theδ(t)function is a very important function in signals and systems and is widely used in communication systems.People define this because of the need of theory,and it does not actually exist in actual engineering.In the current specific definition of the function,a huge fuzzy point is generated,which leads to the thinking of this article.The blur point is how the width of the impulse function is defined.In order to solve the fuzzy points,the following derivation and proof are made,and the research on the fuzzy points is verified.Finally,a reasonable explanation is obtained.
