Suppose a continuous time voice signal x(t) captured by the microphone on a phone can be described by the function : >> x(t) = 3cos(60Tt)+10cos(340TTT)+sin(660Ttt) Find the following: (a) frequency components in x(t) and rate at which the signal should be sampled for it to be fully recovered at the receiver. (b) number of samples that will be obtained after 80s when the signal x(t) is sampled at 200 Hz and the discrete signal x[n] in its simplest form (minimum or alias frequency) (c) the discrete frequency content of the signal x[n] (d) (d) do you think the signal x(t) can be fully recovered?
