Fourier series quiz9

Fourier Series - QUIZ

Fourier series

16. Team B: If we were to represent the function below as a Fourier series what could you say about the value of a0 ?

a0 is baseline shifter. Half way between 20 and 70 is 45. So ao = 90

18. Team B: If we were to represent the function below as a Fourier series what could you say about the value of the b1 term ?

It would have a negative amplitude


Finding coefficients of the fourier series quiz

Finding coefficients of the Fourier Series - QUIZ

Find Fourier series to represent this repeat pattern.

Steps to calculate coefficients of Fourier series

1. Write down the function f(x) in terms of x. What is period?

Period is 2p

2. Use equation to find a0?

Team A find coefficients an?

3.

4.

Team B find coefficients bn?


Finding coefficients of the fourier series quiz1

Finding coefficients of the Fourier Series - QUIZ

Find Fourier series to represent this repeat pattern.

Period is 2p

Team A find coefficients an?

3.

Integrate by parts

so set u = x and cos (nx) dx = dv

and du = dx
