Question 1.
What is the Fourier transform of the Dirac delta function?
Show hintHide hint
This signifies a representation across all frequencies.
Question 2.
What does the inverse Fourier transform of 1 yield?
Show hintHide hint
Think about what the delta function represents in the time domain.
3Question 3.
What is the Fourier transform of the Dirac delta function?
- 0
- 1
- δ(x)
Show hintHide hint
Think of it as having equal contributions at all frequencies.
4Question 4.
True or False: The inverse Fourier transform of 1 gives δ(x).
- True
- False
Show hintHide hint
Consider the relationship between constants and impulses.
Question 5.
A system is subjected to an instantaneous force represented by F(t) = F₀δ(t). How does this affect its response in the frequency domain?
Show hintHide hint
Consider how the delta function impacts system behavior at different frequencies.
Question 6.
For a given signal represented as x(t) = A * δ(t-t₀), calculate its Fourier transform and interpret the result in engineering terms.
