Question 1
What does the Fourier Transform do?
- Transforms time-domain signals to frequency domain
- Transforms spatial-domain signals to time domain
- Both time and spatial transformations
💡 Hint: Focus on what domain the signals originate from.
Question 2
True or False: The Inverse Fourier Transform allows us to obtain the original signal from its frequency representation.
- True
- False
💡 Hint: Consider it a way to revert back to the original function.

Question 1
Given a continuous function f(t) = cos(t) defined for all real numbers, compute its Fourier Transform and explain the result.
💡 Hint: Focus on how trigonometric functions are represented in frequency.
Question 2
Using Parseval’s Theorem, prove that the total energy of a signal in time equals its total energy in frequency.
💡 Hint: Use the relationship defined in Parseval's Theorem explicitly.
