摘要
地球物理专业的重要课程"信号分析与处理"知识体系庞杂,公式繁多,是较为难学的一门课程。文中论述了"信号分析与处理"课程理论体系,重点分析了几个重要概念:转移算子、系统函数和冲激响应,并阐述了他们之间的内在联系。明确了这门课程的核心概念是系统的转移算子,通过转移算子可以把整个课程的主要内容串联起来。
The key course tor geophysics " signal analysis and processing" contains lots of concepts and equations, which is really difficult for studying. This paper discussed the theory system of " signal analysis and processing", and analyzed a tew important concepts: transter operator, system function and impulse response. Moreover, the inner relation among them was discussed, and the key concept "transter operator" was emphasized. All contains of this course could be associated together by the transter function.
