Question

A) B5 is logic circuit for a warning system for a greenhouse. Once the gardener or caretaker has switched the system on, he wants to be warned by the following conditions:

  1. if the greenhouse gets too cold or
  2. if someone has opened the door.

 

Fig B5

Use the figure to answer the flowing questions:

  1. Verify using truth table the conditions that may trigger a warning light.
  2. Develop a Boolean expression for the system in fig B5

B)

A coin-operated cold drink dispenser will provide cold drink (D) under the following conditions:

  • The correct coin (C) is inserted AND
  • A paper cup is in position (P) AND
  • The selector is set t Orange (O) OR Sprite (S) OR Lemonade (L)

 

  1. Write the Boolean expression for the output of the dispenser.
  2. Represent the operation of the dispenser in logic circuit

4 get a logic circuit to mimic aorporate checquing system for operatore of a compnny

 

 

 

  1. It is your responsibility to;
  2. Comply with the general information and instructions given on the question paper.
  3. Ensure that your answers follow the required format.
  4. Submit your final document (answers) following the online submission procedure below and
  5. Provide thew required information on the submission cover page (students full Name, index number, Campus, session, course code, and title)
  6. Because final submission is based on access to the internet, avoid last minute work and submissions. You should expect huge traffic on all networks (ISP’s) and the platform close to the submission deadline. Therefore, you are advised not to wait until the last minutes before you submit your work.
  7. Note that no submission will be entertained after the deadline.
