(a) Design a half-subtractor circuit with inputs x and y and outputs Diff and B out . The circuit subtracts the bits x – y and places the difference in D and the borrow in B out .
(b) Design a full-subtractor circuit with three inputs x , y , B in and two outputs Diff and B out . The circuit subtracts x – y – B in , where B in is the input borrow, B out is the output borrow, and Diff is the difference.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
