摘要
以数学模型、线性时不变性、变换域、频谱、系统函数等概念为基础，通过连续和离散、时域和变换域之间的对比，同时强调数学表达式的物理含义和工程应用等来进行信号与系统的课程教学。实践表明，该方法有助于提高教学效果。
This paper mainly introduces how to carry out course teaching of signal and syetem based on concept with the examples of mathematical model, linear and time-invariance, transform domain, impulse signal, the spectrum and system function, through the comparison between continuous and discrete, time-domain and transform domain. While stressing the physical meaning of the mathematical expression and application in engineering. Practice shows that this method can erectlyely improve teaching effect.
