傅里叶级数理论关注的问题是,一个给定的周期函数,如心跳图或射电脉冲星信号,是否可以写成简单波的和。一个简单的波在数学术语中被描述为csin (2πkx)或ccos (2πkx)对于整数k和实数或复数c的函数。
The theory of Fourier series is concerned with the question of whether a given periodic function, such as the plot of a heartbeat or the signal of a radio pulsar, can be written as a sum of simple waves. A simple wave is described in mathematical terms as a function of the form csin (2πkx) or ccos (2πkx) for an integer k and a real or complex number c.
