Digital Design 2: Truth Table and Boolean Expression from a simple problem description.

This video shows how to derive a truth table and Boolean Expression from simple problem statements.

This is the perfect video that throws light on the subject.

My friend, you just made Boolean algebra much more fun to me. Thanks a lot and please continue this videos

Holy crap my prof confused the hell outta me, this vid put everything together for me. Thanks so much!

1. A conveyor system brings raw material in from 3 different sources. The 3 sources converge into a single output conveyor. Sensors mounted adjacent to each source conveyor indicate the presence of raw material.
All 4 conveyors have separate motors so they can be individually controlled. Each source conveyor can have different speed.
The output product flow rate is fixed; it can be turned only on or off. The output product rate must match the source flow rate to accomplish this following conditions must be met.
1. If source 1 has product, then source 2 and 3 must be turned off.
2. If source 1 is empty, then either 2 or 3 or both can be turned on.
3. In the event that no product is available from the 3 sources, the output conveyor must be turned off.
4. If no product is available, the respective source conveyor must be turned off.
A) Construct the truth table

What's the simplified form of A'BCD+AB'CD+ABC'D+ABCD'?

How could I solve a problem where I have to create a circuit for a 4 sided die game. For each round both players will roll a single 4 sided die. The player with the higher number wins, however can only win if the numbers are consecutive like: Player1 rolls a 1 & Player2 rolls a 2 or Player1 rolls a 2 and Player2 rolls a 3. I can only use AND, OR, NOT, NOR & XOR with a max. of 2 inputs. While the outputs need to be marked as P1 and P2 as two LEDs, so that when Player P1 wins the it's LED lits up and if P2 wins it LED lits up but if no player wins then no output LED should be lit. I know that overall there are only 6 cases of wins and three for each player. Please could you give some advice or video if possible on ways how to approach this word problem. Thanks.

has to be on the back porch is also another variable??? this is why i dont like these word problems

[Zicagory]

He was trying to use a general steps for other problems to be understood :)

you have made it very complicated when the solution is already in the word problem.: Dark AND Motion OR Switch. Using your symbols, that translate to : DM + S which can be read as (D AND M) OR S. Because of the Commutative Property, S + DM is also an equivalent. Hope this clarifies a bit.

Those should be don't cares for the switch...
