matlab离散傅里叶变换平滑代码数字信号处理实验室代码 Matlab代码,用于DFT,IDFT,脉冲,采样定理,自相关,线性和圆形卷积等功能。 DFT 离散傅里叶变换(DFT)是用于数字信号处理中数值计算的主要变换。 它非常广泛地用于频谱分析,快速卷积和许多其他应用。 DFT将N个离散时间样本转换为相同数量的离散频率样本,并定义为 DFT之所以被广泛使用,部分原因是它可以使用快速傅立叶变换(FFT)算法非常有效地进行计算。 代号 逆DFT(IDFT)将N个离散频率样本转换为相同数量的离散时间样本。 IDFT的形式与DFT非常相似,因此也可以使用FFT高效地进行计算。 冲动 在信号处理中,动态系统的脉冲响应或脉冲响应函数(IRF)是动态系统的输出,当出现短暂输入信号(称为脉冲)时。 更一般地,脉冲响应是任何动态系统对某些外部变化的React。 采样定理 连续时间信号可以在其样本中表示,并且可以在采样频率fs大于或等于消息信号的最高频率分量的两倍(即fs≥2fm)时恢复。 自相关 自相关,也称为串行相关,是信号与自身的延迟副本之间的相关关系,它是延迟的函数。 非正式地,这是观察之间的相似
