Due: February 28, 1130 hrs

Work in groups of TWO from within your own set.
 

Part A.

(1). An electric pump circulates water through the radiators of a central heating system. The
      pump will have a signal input which must be set to a high state when the pump is to be
      turned on. This pump should operate only when a time switch is on (high) and the room
      temperature is below a pre-selected level (this will be indicated by a thermostat being in a
      high state). There are a total of two rooms each with their own thermostat and the pump
      should be on if either of the thermostats is on.

      Design a a circuit that will operate the pump based on the criteria above using
      combinational circuits . Provide a truth table and your circuit design.

(1). Solve and hand in the following problems from your textbook :

 Chapter 3: 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 15, 16, 18, 21, 22, 23, 24
