One important takeaway from this formula is that the series composition of a square wave only uses the odd harmonics. This stems from the fact that a square wave is an odd function, which has important implications on measuring signals of this sort. Given a 1 Gb/s square wave, the bandwid...

Creating a square wave from a series of sine waves (4.53)f(t)=sinωt+1nsin(nωt),n=1,3,5,7,…,∞ The first term on the right side of Equation 4.53 is called the fundamental frequency. Each value of n is a harmonic of the fundamental frequency. Looking at Figure 4.13, we can...

Fourier series--square wave Fourier series--triangle wave If a function is even so that , then is odd. (This follows since is odd and an even function times an odd function is an odd function.) Therefore, for all . Similarly, if a function is odd so that , then is odd. (This...
Fourier Series of Even Square Wave Homework Statement -0.5\leq{t}\leq{1.5}, T=2 The wave is the attached picture. I need to determine the Fourier Series of the wave in the picture. I know that f(t)=a_0+{\sum}_{n=1}^{\infty}a_ncos(n\omega_0t)+{\sum}_{n=1}^{\infty...
Fourier Series: Square WaveAlain Goriely
*[Equation 7]* All of these represent the correlation of the function f(t) with the basis sine and cosine functions. For the specific square-wave f(t) of Figure 1, the optimal values come out to be: Note that all of the a_m values (except a0) turn out to be zero. The simple ...
Laplaces Equation with Fourier Series Ok, I'm going to bed. But I have to ask ANOTHER question about my homework... so I can get up early and work on it. Q: Around the unit circle suppose u is a square wave: u_0 = \left\{\begin{array}{c} +1 \,\,\,\, on\,the\,upper...
