Design a low-pass filter that attenuates the frequency of 100 Hz and passes the frequency of 30 Hz at a sampling rate of 1 kHz. The impulse response of the filter should end before the 100th sample. Which of the following options represents the correct design of the filter? 1) Option A: Set the cut-off frequency at 100 Hz and e a filter order of 5. 2) Option B: Set the cut-off frequency at 30 Hz and e a filter order of 5. 3) Option C: Set the cut-off frequency at 100 Hz and e a filter order of 10. 4) Option D: Set the cut-off frequency at 30 Hz and e a filter order of 10.
