Hi all

Can anybody give some inputs or ideas to design this one below :

A water well pump is to be turned on automatically if the water level is low in
any two or more of the three reservoirs it supplies. Each water level detector
in the reservoir generate logic 0 if the level in the reservoir is low.
(a) Draw the truth table for the above function.
(B) Express the output in SOP form.
© Minimize the expression using Boolean laws.
(d) Verify part © by minimizing the expression using K-map.
(e) Realize the digital circuit using NOR & OR gates only.

Thanks and regards

Listen, I understand there are language barriers sometimes, but people are put off by rude statements. In fact, someone who comes across as rude, demanding, or otherwise unfriendly may never get an answer.

In homework help, it is expected that you first attempt to get an answer in your own and present that work in your post. I often joke that this forum is NOT homework done for you. Secondly, rather than presenting an entire problem (quoted verbatim), it's best to break the problem into smaller pieces.

Hope you are not offended , but I am really trying to help.

You have resurrected a ten year old post! Are schools still setting the same old questions?
