Oscilloscopes - Fourier Series of a Square Wave (and Why Bandwidth Matters) It will be explained the occurrence of ringings in a signal from the perspective of the underlying theory (Fourier series as a method for solving partial differential equations), and then relate it back to using an os...
(这可能会很大,对于方波函数(square wave)来说,过冲大约在 \delta = 0.18A)。当越来越多的项数被加到泰勒级数中,震荡会越来越接近非连续部分,但是特征幅度保持一个常数。这个现象被称为吉布斯现象。 (a)吉布斯现象;(b)在更精细的时间尺度上显示(a)的不连续性,但增加了更多的项。 帕斯瓦尔定理(Parseval's ...

Example Find the Fourier series representation of a ‘square wave’ signal given by ft=−1,−π≤t<0;1,0≤t≤π. where f(t + 2π) = f(t). In this case, a01π∫−ππftdt=1π∫−π0−1dt+1π∫0π1dt=0, an1π∫−ππftcosntdt=∫−π0−1cosntdt+∫0π...
File:Fourier Series.svg The first four partial sums of the Fourier series for a square wave In mathematics, a Fourier series decomposes periodic functions or periodic signals into the sum of a (possibly infinite) set of simple oscillating functions, namely sines and cosines (or complex ...
a square wave = sin(x) + sin(3x)/3 + sin(5x)/5 + ... (infinitely) That is the idea of a Fourier series. By adding infinite sine (and or cosine) waves we can make other functions, even if they are a bit weird. You might like to have a little play with: ...
One of the most common functions usually analyzed by this technique is the square wave. The Fourier series for a few common functions are summarized in the table below. function Fourier series Fourier series--sawtooth wave Fourier series--square wave Fourier series--triangle wave If a ...
