4Question 4.
True or False: DFT applies to continuous signals.
- True
- False
Show hintHide hint
Think about how signals are sampled.
Question 5.
How would you apply FFT to a signal contaminated by noise? Describe the steps involved.
Show hintHide hint
Remember the steps of transformation and filtering.
Question 6.
Imagine you have a signal with frequencies at 60 Hz and 120 Hz. If FFT shows leakage what could be the impact on signal interpretation?
Show hintHide hint
Think about how alignment affects frequency clarity.
