摘要
基于离散哈脱莱变换与离散傅里叶变换关系计算非周期信号的频谱 ,该方法与利用离散傅里叶变换的大多数算法相比优点是能减少运算量 ,提高运算速度。
A new of method of computing frequency spectrum of non periodic signal is obtained by using the relations of DHT and DFT. This method can reduce computational burden and reach a high computation speed compared with a majority of algorithm of the DFT.
