5 that the impulse response of a LTI system is the inverse Fourier transform of the frequency response . The immediately apparent difficulty in the calculation of h(t) is that the function H(蠅) is a complex function of 蠅 in the general case. The integral cannot generally be evaluated ...

In this paper, it is shown that every continuous linear time-invariant system L defined either on L p or on D'L p (1lesplesinfin) admits an impulse response DeltaisinD'L p' (1lesp'lesinfin, 1/p+1/p'=1). Schwartz' extension to D'L p distributions of the usual notion of convolut...

1、连续时间LTI系统的复频域描述 拉普拉斯变换(The Laplace transform)主要用于系统分析。描述系统的另一种数学模型就是建立在拉普拉斯变换基础上的“系统函数(System Function)”——H(s): 5.1 系统函数 的实质就是系统单位冲激响应(Impulse Response) 的拉普拉斯变换。因此,系统函数也可以定义为: ...
