Mathematica definitions

DTFT vs. DFT: Example #1: 1Hz cosine wave

DTFT vs. DFT: Example #2: 1Hz cosine wave (higher fs)

DTFT vs. DFT: Example #3: (1+1/6)Hz cosine wave

DTFT vs. DFT: Example #4: (1+1/6)Hz cosine wave (higher fs)

DTFT vs. DFT: Example #5: sum of cosine waves (DC, 1Hz, 2Hz)

DTFT vs. DFT: Example #6: sum of cosine waves (DC, (1+1/6) Hz, (2+1/6)Hz)
