Suppose a 18-bit digital representation of an analog signal with amplitude of 10 v (i. e., signal can vary from +10v to –10 v) is to be used. n =18 bits would allow for a huge dynamic range of amplitudes, from the smallest binary number (2^0 = ) to the largest binary number of (2^n–1 = ), for a dynamic range of db. this corresponds to an amplitude resolution (step-size) of (20 v)/(2n-1) = v.

How to tell if a molecule is polar or nonpolar with electronegativity

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
