Question

how to calculate fourier transform and fourier series

Answer 1

This is a very vast chapter so I suggest you to follow the book written by B S Grewal. You can understand it in very easy way.

Answer 2

Answer:

Key Concept: Relationship between Fourier Series and Fourier Transform. Note: The Fourier Transform of xT(t) is given by: XT(ω)=2π+∞∑n=−∞cnδ(ω−nω0) X T ( ω ) = 2 π ∑ n = − ∞ + ∞ c n δ ( ω − n ω 0 ) . These relationships are spelled out on a one-page pdf.
