Y ( t ) = 9 c o s ( 1.5 π t ) + 0.7 c o s ( 2 π t ) v o l t s is sampled at a rate of F S = 2 H z to produce the sampled vector y – = [ 9.7 , − 7.06 , 0.7 ] v o l t s and then quantized. Assume, as usual, the minimum voltage of the dynamic range is represented by all zeros and the maximum value with all ones. The numbers should increase in binary order from bottom to top. Find the bit combination used to store each sample d [ n ] , n = 0 , 1 , 2 when rounded to the nearest integer between − 8 and 7 v o l t s (clipping may occur).

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
