Question 5 (10 pts): Signal multiplication. Plot discrete signals x[n] (3 points) , h[n] (3 points) , and y[n]=x[n] · h[n] (4 points) where, x[n] = u[n + 3] − u[n − 3] h[n] = 2 · (1/2)n · u[n]

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. For a system to be stable, a bounded input signal should lead to a bounded output only for future time.

Carbohydrate digestion begins in the with the enzyme

True or False: Glycogen synthesis is lowest immediately following exercise; ideally the athlete should wait at least 4 hours after exercise before they replenish carbohydrate stores

_____________ represent the most elemental form of carbohydrates and require no additional digestion to be absorbed into the blood. 

__________ is released when blood glucose rises, to make extra blood glucose available to the cells

When energy needs are met and glycogen stores have been fully topped off and maximized, what happens to excess carbohydrates that are ingested?

Upon dental charting, you notice a restoration that is white and located on the occlusal of the tooth and continues over the edge to the mesial side of the tooth.  How would you report this to the dentist?

A major risk factor for caries and periodontal disease is:
