Q1. For each of the following signals: x(k) = tan(0.707 pi k) [(k) (k 100)] x(k) = (k) + cos( pi k) (1) k x(k)
Q1. For each of the following signals:
- x(k) = tan(0.707 pi k) [(k) (k 100)]
- x(k) = (k) + cos( pi k) (1)k
- x(k) = sin( 0.5 pi k)/(1+ k2)
- x(k) = j2k
- x(k) = k2/(1 + k2)
- Classify each of the following signals as bounded or unbounded.
- Classify each of the following signals as periodic or aperiodic.
- Classify each of the following signals as finite or infinite. For the finite signals, find the smallest integer N such that x(k) = 0 for |k| > N.
- Classify each of the following signals as causal or noncausal.
