c) The continuous time signal: x(t) = cos(2n. t) + sin(2n. t) is correctly sampled at fs = 2Hz. The sequence x[n] is the sampled version of x(t)). Find the first 6 values in x[n]. Evaluate the energy and power in the sequence x[n] over the sample values n=0 to n=5. Will the complete x[n] over n = 0 to n = inf inity be a power or an energy signal?
