摘要
本文提出了离散余弦列率滤波的卷积算法,推导了离散余弦列率滤波器(DCSF)的设计公式。这种新型的线性相位数字滤波器可使传统列率滤波得到简化且避免波形失真。
A convolution algorithm for discrete cosine sequency filtering (DCSF) are proposed in
this paper. Formulas for designing discrete cosine sequency filters are derived. These new linear
phase digital filters can simplify conventional sequency filtering and avoid waveform distortion.
