# Find Fourier Series Coefficients

1. Find Fourier Series Coefficient for a signal. (alternanate sawtooth pulse from t= -3 to 3 amplitude 1 on positivwe side and-1 on negative side. 3 pulse on positive side. 3 pulse on negative side. pulse width is 1.) as given in attachment file.

2. Compute the fourier series coefficients a[/k], b[/k], and x[k]. Simplify for odd K aand even K.

3. Compute the signal Power in the fundamental component.

4. Compute the signal Power upto the fourth harmonic.

5. Compute the total signal Power.

There is an equation for calculating Fourier series coefficients. You should be able to find it in either your text book or class notes.

i am weak student so im not able to find out so plese help

The equation will be near the beginning of wherever your textbook first begins discussing Fourier series. It involves doing an integral -- if f(t) is the signal, look for something sort of like this in the equation:

$$\int f(t) \cdot \sin(\frac{2 \pi}{T}t) \ dt$$

or a similar expression with cos instead of sin.
