This series expansion is called a Fourier series expansion or simply a Fourier series. Let us look at the Fourier series of the following function: (2.5)f(x)=cosx(−π2≤x≤π2) A function f(x) is a function of period 2L = π (see Figure 2.15(a)). From the formulas (2.2), ...
The Fourier series expansion for a rectangular pulse wave with period T, amplitude A and pulse length τ is (FFT_algorithm; Harmonic): (6)x(t)=AτT+2Aπ∑n=1∞(1nsin(πnτT)cos(2πnft)) where, f=1T , if duty cycle d=τT is used, and ω=2πf, then Eq. (6) can be ...
