tbh.... I need to download all of your videos because I'm afraid if something will happen to such treasure. I aid my self-study with your videos and it makes such a wonderful impact/experience, huge thank you! I really feel like you love what you are doing, and that shows in a way how you explain things...

That's the way all tutorials should be made. Clear and fluent language, without breaks, all words fully understood and the fluent of speaking at the correct speed. None pauses, coughs or mistakes. Enough with all tutorials and courses, plenty of them highly paid, that we need a translator or subs in order to understand most of the words. Golden rule? If you cannot speak correct and understood English, prefer to make videos only to the mother tongue.

The fundamental concepts have not changed since the 1950's. Some people use different symbols for the logical operations. I have used ^ for AND, v for NOT and ¬ for NOT because you can find them all on a keyboard. The fundamental concepts are universal, regardless of the syllabus you follow :)KD

Please correct me if I'm wrong, but the logic circuit you drew from the Boolean expression Z=(A and B) and NOT B is incorrect. If B is high than the circuit will not have an output due to the NOT gate feeding the second AND gate. If B is low than the first gate will not have an output, which will cause the second gate to again have no output. B can not be high and low at the same time in an AND gate configuration.

@ComputerScienceLessons

6 жыл бұрын

Hi James. The logic gate diagram does indeed match the expression (the object of the exercise), but as you have quite correctly pointed out, the circuit is pretty much useless. Examination of the truth table reveals that the value of Z is always 0, which means the whole thing could replaced with a single wire carrying no voltage at all. A B NOT B Z 0 0 1 0 0 1 0 0 1 0 1 0 1 1 0 0 If you are interested, my videos on Karnaugh maps and Boolean algebra cover techniques for simplifying expressions and therefore the circuits they represent.

I have the second of three on Boolean algebra (simplifying complex expressions using the laws) almost ready to upload. There will be a third on using De-Morgan's theorem. Please watch this space. You might also want to take a look at my playlist on Karnaugh Maps which is closely related. kzread.info/head/PLTd6ceoshprcTJdg5AI6i2D2gZR5r8_Aw

Yes it is. This is known as the commutative law of Boolean algebra. However, not(a and b) is something different. Furthermore not(b and a) is the same as not(a and b) :)KD
