Question: the continuoustime sinusoid rt 05 cos2rt 53cos ...

Question details

The continuous-time sinusoid r(t) = 0.5 + cos(2rt +5)+3cos( ) COS is uniformly sampled with sampling time T, seconds, resulting in the discrete-time sequence [n]. 1. For what range of T, can (t) be sampled without aliasing effects? (1 pt) 2. Let T, = 1/4 seconds. What is the fundamental period MO of the (2 pt) resulting periodic sequence r[n]?
