As a small child in the 1970s, I remember my Father demonstrating logic to me by building a 4-bit adder, using indicator-lamps, toggle-switches, and relays, all mounted on an aluminium frame. Lots of neatly soldered wires all laced together into bundles with waxed string, telecoms style. He used to work for the UK's Post Office Telecommunications, back when they ran the national phone system (before BT was formed), then he taught electronics.

[@mahmoody4200]

This was the exact same experience i had with my father back then in the 90s, he also worked in Morocco Post office telecommunications, and thought himself electronics by correspondence he used to do DIY electronic board projects. To this day i look back at those memories with great amazement.

Hey Mehdi. I don’t know if you ever look back through comments, but if you do I want to say a massive thankyou. I’m 34 and have spent my life as an electrical installation engineer, now following an injury I’ve retrained as a design engineer and continue to search for a career in something I feel so passionate about. This video, just like all your videos has inspired me to learn different aspects of electrical and electronic circuitry that I never considered before, and continue to expand my knowledge. I now want to get a deeper understanding of Logic! Anyways, keep up the great work mate. 100% best channel on KZbin 👍🏻 Once again, many thanks.

[@Simmons101]

Thank you for another elegant and fantastic crash course video! This perfectly summed up the basic fundamentals of my Digital Logic and Design course at University. One thing thats really interesting is using transistors to make switches and gates. When we use PNP or NPN transistors to make gates our professor highlighted that it's impossible to make native AND and OR gates due to how the transistors work with logic. We can make NAND and NOR gates really easily however, so we just use an inverter on the output of inverted logic gates go make them normal gates. Though we can use boolean algebra to determine if it's a good idea to do so, or if we save transistors by using NAND, NOR, and XNOR gates instead.

[@EdwardMillen]

Wow! Up until now I didn't really fully understand how logic gates worked... or at least I thought I didn't. I stopped doing electronics in school (or rather, the electronics teacher left and they never replaced him) before they got as far as anything like this, and I didn't really get any further into electronics myself after that, but I was properly getting into programming at around the same time. After just the first few minutes of this video, I've realised that logic gates work exactly the same way as if statements (which I'm very familiar with), just with specific names for different types, and you've explained what each name translates to so now (if I ever needed to) I would know exactly how to use them!

[@MasterGeekMX]

As a computer sciences student: excellent job. We see this on the introduction to computing and computer architecture class. Also, in programming languages AND, OR and NOT are widely used. In most languages, AND is expressed as &&, OR as || (nor an L, it is the vertical bar) and NOT as !. so the XOR equation at 4:53 will be Q = (!a && b) || (a && !b)

[@Atlas_Enderium]

What languages use && for AND and || for OR? I am currently only familiar with conditional statements and Boolean logic in Python, which uses just “and” for AND and “or” for OR

[@keeleyhoek]

@@Atlas_Enderium All C programming language derivatives: C, C++, Java, C#, Rust, Javascript, Swift, PHP, Ruby, Dart, etc. (basically everything in common use except python)

[@eneg_]

@@Atlas_Enderium python also uses & and | as operators, albeit they are "bitwise". Operations on bits of integers as well as on hashed data structures like dicts and sets can be done using those. I assume you haven't used sets yet, so go have a read.

[@jeremypnet]

Actually, for any C like language that has a proper Boolean type, xor is more easily expressed as a != b and xnor is a == b. It doesn’t work for C itself because you can treat any integral type as a Boolean including pointer types.

This is such a great intro to computer logic that my entire logic and computing design class just flashed before my eyes XD!! Loved the example for the And gate hahaha… Also… the propogation delay glitch… I’m just realizing that having a rats nest of wires on my breadboard may be why some of my more complicated Logic lab projects didn’t work even though my connections were correct (I checked time and time again lol). We had IC’s to keep things sort of compact, but transistors are sensitive and these chips are better behaved when soldered to a more streamlined circuitboard. So between the rats nest of wires slowing things down and god knows how many broken connections in the breadboards (used for generations in a lab full of newbies like me at the time) no wonder some of the projects wouldnt work no matter how hard I tried hahaha

[@yeppiidev]

hmm

[@JayOhm]

Propagation delay of wires wouldn't affect transistor gates. Especially not CMOS ones. If it does the circuit design sucks. Poor contact, on the other hand, can mess things up a lot, especially with TTL. And on a solderless breadboard it is pretty much guaranteed. Once I even had an OpAmp *explode* in my face due to poor contact elsewhere. Having said that, even perfectly soldered logic can easily have propagation delay glitches. You have to assume those delays can randomly vary orders of magnitude. That's why synchronous logic is often so much easier. A circuit without feedback will settle eventually, and then you just latch the results and can safely reuse them as inputs to the same circuit. Wait until it settles (usually for one cycle of a fixed clock), latch, repeat. Especially relevant for FPGAs where propagation delays are especially huge and random.

[@akashghosh1151]

@@JayOhm thanks for te info good guy i have been learning vlsi coding and propagation delay always comes back in form of something in the verilog designs

[@pyro-millie5533]

@@JayOhm contact issues most likely caused it then. As I said, we were newbies and probably broke our fresh breadboards, and the school's equipment that we plugged our stuff into was generations old, so god knows how many broken contacts that had lol

Its incredible that a profesor in a tecnical uni cant teach logic in circuits in a semester but you just did it in a 15 min vid with more entusiasm and actually made focus on the tppic, medhi(idk if i wrote it right) could be one of the best profesors out there

This is one of the best descriptions of computer logic I've seen, well done Mehdi! Now you just need to make something with your switch logic...like ARTIFICIAL INTELLIGENCE!!! ...or maybe just a simple calculator for now...

[@HECKproductions]

bonus knowledge: -if you connect the two inputs of a nand gate you have an inverter -if you invert both inputs of a nand gate you have and or gate this means that you can make any type of gate you want with just nand gates there is actually a "discipline" of logic called nand logic or something because its cheaper to use an ic that just has loads of nand gates on it and you can make any other gate with them anyway

Hey, _I_ watched the relay video. It was great. Boooolian math hurts my old brain but this video was useful. It gave me an idea for a light delay I would like to make for a door switch. Sure, I could use an off the shelf controller, but where's the fun in that?

I don't think boolean Algebra can help you make a delay circuit

Logic is so fascinating. And can be to maximum complexity when it comes to CPUs.

[@user-vn7ce5ig1z]

With a little thought, you can figure out ways to break down all kinds of different problems to mere logic problems and then solve them. "When will we use this in real liiiiife? 🙄" You never know when you'll suddenly realize that you can solve a real-world problem with a simple Karnaugh map. Been there, done that. 😉

[@Totone56]
