摘要
卷积技术是信号与系统分析的核心技术。它在LTI时域和频域系统分析中起着重要作用。通过用卷积技术计算因果系统的冲激响应、零输入响应、零状态响应及全响应的算法分析,最终推导出了基于卷积技术的非因果激励和非零初始条件下的LTI系统响应的时域算法,该算法是用傅里叶变换或拉氏变换分析LTI系统的依据。该算法的运用使LTI系统响应的时域分析走向频域分析。
Convolution is a key technique in signal and system analysis, which plays an important role in LTI time and frequency domain analysis. By using convolution technique to calculate cause and effect system＇s impulse response, zero-input response, zero-state response and total response, the paper deduced time domain algorithm of LTI system response under the condition of no cause and effect system and no zero-state at last. The algorithm is a basis that analyses LTI system by Fourier transformation or Laplace transformation.
