The Acme Community Hospital has hired you to redesign the Toxic Waste control circuit for their latest Waste Disposal System. The Waste control circuit is equipped with three sensors A, B and C that output a logic (1) whenever a flame is present. These sensors are connected to fuel inlet which outputs a (1) to the emergency Waste shut-off valve to keep the waste flowing (i.e., a zero will turn the valve off). The original design of the Waste control circuit was quite simple. For the Waste valve to remain on, all three sensors needed to output a logic (1). During field testing it was discovered that variations in gas pressure and humidity cause the thermal sensors to occasionally output a logic (0) even when a flame was present. This caused frequent unnecessary shut downs. For the redesign, it has been determined that the emergency shut-off value should remain open as long as two of the three sensors indicate that a flame is present. Design a combinational logic circuit that meets the above detailed design specifications. a. Create a truth table that captures the functionality of the Waste Control circuit. b. Draw the logic diagram of the un-simplified circuit c. Simplify the equation. d. Draw the logic diagram of the simplified circuit
