Consider the following discrete-time system: y[n] = 100 x[n] cos(0.45πn + 0.5π)
(a) Determine if the system is linear, time-invariant, causal and stable. Justify your answers.
(b) Find the impulse response h[n] for the system and sketch the waveform.
(c) Draw the system block diagram using adder, multiplier and delay elements.
