Featured on Meta Stack Overflow for Teams is now free for up to 50 users, forever Fourier series simply states that, periodic signals can be represented into sum of sines and cosines when multiplied with a certain weight.It further states that periodic signals can be broken down into further signals with the following properties. The signals are sines and cosines; 2017-08-23 2005-09-21 6.082 Spring 2007 Fourier Series and Fourier Transform, Slide 22 Summary • The Fourier Series can be formulated in terms of complex exponentials – Allows convenient mathematical form – Introduces concept of positive and negative frequencies • The Fourier Series coefficients can be expressed in terms of magnitude and phase – Magnitude is independent of time (phase) shifts of x(t) Fourier Series of Even and Odd Functions - this section makes your life easier, because it significantly cuts down the work 4.
