# Fourier transform and invese FT of signals

Not what you're looking for?

I have attached some problems that I think I am working correctly. I wanted to verify the concept is correct.

A signal x(t) = exp(-t)*cos(3t) is turned on at t = 0. What is its Fourier transform?

Consider the signal in problem 6. What is the Fourier transform of its derivative with respect to time?

What is the Fourier transform of x = exp(-pi*16t^2)?

What is the inverse Fourier transform of X = cos(f)?

What is the inverse Fourier transform of X = cosh(f)?
