7. At laundromats, using coins and/or pre-paid cards will turn on a dryer machine which consists of a heating source and a motor that turns the inner cylindrical chamber where the wet fabrics are placed. Once a certain amount of time has passed, the dryer will automatically turn off. a) Please create a combination logic gate using AND, NOT and/or OR logic gates that would simulate the logic gate circuit necessary to produce the same outcome as a timed dryer machine. Be sure to properly label and explain your logic gate system. b) Please create a combination logic gate using only NAND logic gates that would simulate the logic gate circuit necessary to produce the same outcome as a timed dryer machine. Be sure to properly label and explain your logic gate system.

Please solve and show work. Will give thumbs up for correct answer.

LOGIC GATE ( NEED ONLY HANDWRITTEN SOLUTION PLEASE OTHERWISE DOWNVOTE).

8. A thermostat for a central air system will control both a heating and cooling system. When a target temperature is set on the thermostat by the operator, it will turn on a heat source if the measured room temperature is below that target temperature. It will also turn on a cooling source if the measured room temperature is above the target temperature. a) Please create a combination logic gate using AND, NOT and/or OR logic gates that would simulate the logic gate circuit necessary to produce the same outcome as a thermostat that controls heating and cooling devices. Be sure to properly label and explain your logic gate system. b) Please create a combination logic gate using only NOR logic gates that would simulate the logic gate circuit necessary to produce the same outcome as a thermostat that controls heating and cooling devices. Be sure to properly label and explain your logic gate system.
