Question 1 of 4
1. Question
Which of the following steps are involved in using the DFT to approximate the FT? Select all that apply.
CorrectIncorrect -
Question 2 of 4
2. Question
Sampling the DFT at a dense set of frequencies reduces the error in approximating the FT that is introduced by truncating the signal in time.
CorrectIncorrect -
Question 3 of 4
3. Question
The error introduced to the FT approximation due to sampling the signal in time can be reduced by increasing the sampling frequency.
CorrectIncorrect -
Question 4 of 4
4. Question
Truncating the signal in the time domain makes the number of samples finite, but causes the underlying DTFT to be smeared by a sinc function.
CorrectIncorrect
