For each of the following signals, where s(t) is in volts: a) (10 points) s(t) = 1 - cos(2t) sin(3t) b) (10 points) s(t) = [cos(2t)] Compute the following quantities: Period (sec), DC and AC components (volts), Total Power (Watts), Theoretical Bandwidth (Hz), and Dynamic power range (DPR) in dBs Hint: No need to evaluate the FSE expansion or power integrals. Use trigonometric identities to convert function into sum of harmonics (plus DC if existing), then add the individual powers for the orthogonal components. No need for integrations!
