What is the formula for the exponential Fourier series?
In order to derive the exponential Fourier series, we replace the trigonometric functions with exponential functions and collect like exponential terms.
This gives f(x)∼a02+∞∑n=1[an(einx+e−inx2)+bn(einx−e−inx2i)]=a02+∞∑n=1(an−ibn2)einx+∞∑n=1(an+ibn2)e−inx.9 juil. 2022The exponential Fourier series representation of a continuous - time periodic signal x(t) is defined as x(t)=∑∞k=−∞akejkωot where ωo is the fundamental angular frequency of x(t) and the coefficient of the series are ak.
