Question 1.
State the linearity property of the Fourier Transform.
Show hintHide hint
Recall how sums are handled in a linear function.
Question 2.
What happens when you shift a function f(x) to f(x - a)?
Show hintHide hint
Consider the effects of time shifts.
3Question 3.
What does the linearity property state regarding the Fourier Transform?
- It's only applicable to periodic functions
- It allows for superposition of transforms
- It has no effect on the outcome
Show hintHide hint
Think about how combining functions behaves in mathematical operations.
4Question 4.
True or False: Scaling a function in the time domain scales its Fourier Transform inversely.
- True
- False
Show hintHide hint
Recall the scaling relationships discussed.
Question 5.
For the function f(x) = sin(ωx), derive its Fourier Transform and discuss the implications of the properties you've learned.
Show hintHide hint
Consider how the sine wave behaves in the frequency domain.
Question 6.
Assuming f(x) is a piecewise function with discontinuities, describe how you'd approach finding its Fourier Transform and include possible issues.
Show hintHide hint
Think about how discontinuities may influence your calculations and if you can re-frame them into a more manageable form.
