How To Find Exponential Fourier Series Coefficients. This version of the fourier series is called the exponential fourier series and is generally easier to obtain because only one set of coefficients needs to be evaluated. C − k = 1 2 ( a k − b k j) = 1 2 ( a k + j b k) c k = 1 2 ( a k + b k j) = 1 2 ( a k − j b k) c 0 = 1 2 a 0.

Second,after having the exact equation or number of vin (t) ,then you'll need to know the laws of circuit analysis or/and methods and know the components. We will use this to determine the fourier series coefficients ck as follows: We must find the d 0 and d n coefficients to find the efs of the signal f.
