This is the next phase of another project, it consists of a python module that allows us to calculate the Fourier series coefficients and sum the harmonic components, regardless of the type of signal. Is a work in progress, I work under the supervision of Dr. Ing. Philip Coanda. The goal of this project is to transform an audio file into a list of values that we can plot and use that signal in our harmonic component gathering application.

The inputs should be m which is the number of periods, and n the number of waves. The function dreptunghi() takes as parameters frequency f, number of samples N and the time base T it should return a list with g the value at the time t which is the discrete time, the increment dt, the number of samples N and the frequency f. The function coef() takes as parameters the signal s, the frequency f, the increment dt and the number of samples N, here is the mathematical logic for the Fourier even coefficients an and odd coefficients bn and forming the lists for waves and it's sum, those two being what the function coef() will return.
