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...
Fourier Series: Square WaveAlain Goriely
Consider a square wave f(x) of length 2L. Over the range [0,2L], this can be written as f(x)=2[H(x/L)-H(x/L-1)]-1, (1) where H(x) is the Heaviside step function. Since f(x)=f(2L-x), the function is odd, so a_0=a_n=0, and b_n=1/Lint_0^(2L)f(x)sin...

残余振荡(residual oscillations)引起过冲(overshoot),其大小是对应的函数的特征。(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 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: ...
Fourier Series - Introduction Fourier series are used in the analysis of periodic functions. A periodic square wave Many of the phenomena studied in engineering and science are periodic in nature eg. the current and voltage in an alternating current circuit. These periodic functions can be analyse...
