What is the Fourier transform of a function?
The Fourier transform is a mathematical function that decomposes a waveform, which is a function of time, into the frequencies that make it up. The result produced by the Fourier transform is a complex valued function of frequency.
What is the formula for Fourier transform?
As T→∞, 1/T=ω0/2π. Since ω0 is very small (as T gets large, replace it by the quantity dω). As before, we write ω=nω0 and X(ω)=Tcn. A little work (and replacing the sum by an integral) yields the synthesis equation of the Fourier Transform.
What is the Fourier transform of gate pulse?
Fourier transform of x(t) is X(ω) expressed as below. X ( ω ) = ∫ − ∞ ∞ d t. G i v e n x ( t ) = 1 f o r t ϵ ( − 0.5 T , 0.5 T ) 0 o t h e r w i s e. X ( ω ) = ∫ ∞ − ∞ x ( t ) e − j ω t d t = ∫ 0.5 T − 0.5 T e − j ω t .
What is the Fourier transform of Coswt?
Therefore, the Fourier transform of cosine wave function is, F[cosω0t]=π[δ(ω−ω0)+δ(ω+ω0)]
