Question 1 (10 pts = 5 questions x 2 points each) Choose the appropriate answers for the following questions. Write your choice clearly.   If x(t) = A cos(ω0 t + φ), then A is: Phase Heart rate Angular frequency Amplitude   Unwanted, often random modifications/additions a signal may suffer during capture, storage, transmission, processing, or conversion are called: Phase Noise DC offset Step function   If x(t + T) = x(t) for a real constant T, then x(t) is: Odd Imaginary Periodic Even   If x = x, then x is: Odd Imaginary Periodic Even   If x = x for an integer n, then x is Odd Imaginary Periodic Even

Question 2 (10 pts = 10 questions x 1 point each) Determine if each statement True (T) or False (F). Write T or F clearly. “White Noise” affects all frequencies equally. The product of a bounded function and an unbounded function is not always unbounded. Biosignals are used in the detection and treatment of pathologies. DC offset is scaling of signal in amplitude. Any signal can be decomposed into odd and even parts. Electrocardiogram (ECG) is an example of a bio-optical signal. Magnetoencephalogram is a measurement of varying magnetic fields. In the transform x(at), a < 1 will stretch the signal x(t) on the time axis. In a general exponential signal x(t) = C eat, C can be complex. A signal can have finite energy and infinite power.

Several years ago, Subway was accused of false advertising with its “footlong” subs when a customer actually measured his sandwich and it was less than twelve inches. Subway’s response was that the bread length can be affected by the baking process and that “footlong” didn’t really mean “twelve inches.” What would you advise Subway do to minimize brand dilution from this situation?
