MAE 2381-001 September 17, 2007 Project 1 1. See Figure 1 on page 2. 2. See Table 1 on page 3. 3. The most realistic representation of Eqn. 2 is case 1. Case 1 has the smallest time interval and over the same period of time will produce more y values than the other cases. The more solutions you have to a sinusoidal equation the closer you come to having all the solutions, and therefore a more realistic representation. 4. Case 3, with a time interval of 0.05 s, yields a saw tooth wave. This is because the sample frequency shows the maxima of the amplitude but very little in between. 5. Case 5. All the y values are so low as the result of the time values relation to sin. 6. A. The sampling frequency is a representation of the true frequency of a wave, but will never be the same because it is not truly continuous. That is to say, the sampling frequency is equal to the true frequency of a wave, but only where the sampling frequency exists according to Δt. 6. B. Since t fs = 1 and the lowest Δt that accurately reconstructed the signal was 0.01 s, 100 = fs . 7. See Figure 2 on page 2. 8.
