A deterministic signal A cos (@ot), where A and wo are real constants, is added to a noise process N(t) for which SNN(W): W² W² + w² and W> 0 is a constant. (a) Find the ratio of average signal power to average noise power. (b) What value of W maximizes the signal-to-noise ratio? What is the consequence of choosing this value of W?
