Specify how many bits are needed to appropriately digitize each of the following signals. Choose from: 6 bits, 8 bits, 10 bits, 12 bits, 14 bits,
or 16 bits.

a. A signal where the maximum amplitude is 1 volt and the rms noise is 1.5 millivolts.
b. A signal with a signal-to-noise ratio of 900 to 1.
c. A signal with a coefficient-of-variation of 0.4%.
d. A high-fidelity audio system (hint: a jack-hammer is about 50,000 times louder than a pin drop).
e. A black and white digital image (hint: under the best conditions, the human eye can differentiate about 200 shades of gray between pure black and pure white).
