A house has two lights to illuminate the stairs leading from the hall to the upstairs landing.The lights can be switched OFF and ON by either one of two switches, one in the hall and one in the landing. The lights are to be OFF when both switches are either ON or OFF together, and the lights are to be ON when one switch is ON and the other is OFF. i) Obtain the truth table of the system ii) Obtain the sum of products (SOP) Boolean expression for the system. iii) Implement the system using AND, NOT and OR logic gates. iv) Implement the system using exactly ONE logic gate.

A fruit processing company wants to install an apple processing plant in Quetta. Company required the design of a system to pack four apples in a box but the apples vary in sizes. For simplicity an apple is characterized as ‘Big’ or ‘Small’ with logic ‘1’ and logic ‘0’ respectively. In this way there will be four categories of boxes so, a color label should be placed on each box to distinguish different boxes. The boxes should be labeled using following rule, If all four apples are small, the box should be labeled red If only two apples are small, the box should be labeled blue If only one apples is big, the box should be labeled green If all four apples are big, the box should be labeled yellow If only three apples are found big, the box should be labeled with both red and yellow. List the truth table. Draw the circuit diagram of system using decoder.
8. We have two push buttons A and B. Design a 3-digit BCD counter that: - counts from 000 to 999 if no button is pressed - Resets the count to 555 if both push buttons A and B are pressed Resets the count to 222 if only push button A is pressed - Resets the count to 333 if only push button B is pressed

The response to the question I have asked here... "2. Sometimes light fixtures are controlled by more than one switch. Circuits need to be designed so that flipping one of the switches turns the light on when it is off, and turns the light off when it is on. Design logical circuit that accomplishes this when there are two switches. Explain, how and why will your circuit work. Please draw the circuit and show logical operations. (Can only use or, not, and)" Does not seem right as what you provided gives a truth table of if both switches are off the light fixture would be on which should not be the case and does not make sense in context of the question asked. Also the circuit drawing doesn't seem right... Can you re-explain cause what you provided as the answer is not making much sense... A' solely being what determines if fixture is on or off does not seem right at all...
