Examine the pulse response h(t) of various different low-pass filters in the time and frequency domain.
A δ-pulse is directed at three different low-pass types with the same cut-off frequency (100 Hz) and of the 10th order. Remember that the one-off δ-pulse contains all the frequencies from 0 to ∝ with the same amplitude.
(a) What frequencies can the pulse responses only contain? What features of the filters can you deduce from the different pulse responses h(t)?
(b) The frequency domain of the pulse response apparently gives the "filter curve" and the frequency response of the filters. Why?
(c) Why is the length of the lower pulse response much greater than that of the other pulse responses? What does this mean from the point of view of the UP?
(d) Design this circuit using DASYLab and carry out the experiments.
A 52-kg pole vaulter running at 12 m/s vaults over the bar. Her speed when she is above the bar is 0.7 m/s. Neglect air resistance, as well as any energy absorbed by the pole, and determine her altitude as she crosses the bar.
Consider the discrete-time sinusoid given by x[n] = A cos(ω n+ φ), where x[n] may or may not be periodic. For it tobe periodic with a period of N, it must satisfy x[n] = x[n + N] forall integers n.
Compare all the filter circuits from the point of view of ripple factor.
