介绍一种实用谐波分析的方法,利用这种方法,在观察值个数相同的前提下,求得的付里叶系数比用常规方法得到的系数有更高的精度,从而使展开的付里叶级数对被展函数有相当满意的逼近。本文给出了这一方法在微型计算机上的实现,并把它与用不同方法所得的结果作了比较。 A method of practical harmonic analysis is introduced. With this method, the Fourier coefficients obtained are higher than those obtained by the conventional method under the same observation number, The Fourier series have quite satisfactory approximation to the developed function. This paper presents the implementation of this method on a microcomputer and compares it with the results obtained by different methods.
