You say it's "awesome" but that it contains inaccuracies. So, which is it? Unfortunately, the example for the active-high RS is incorrect. Either the SET and RESET need to be swapped or the Q and Q-NOT need to be swapped. It is IMPERATIVE when making instructional videos to be accurate or it will just confuse the viewer. How does anyone , in the know, miss that the output of a NOR gate cannot be HIGH if either of the inputs is HIGH? (3:10)

The diagram for the NOR gate RS flip flop is incorrect. The SET input is on the NOR with Q-NOT output and the RESET is on the NOR with Q output. There is no way for Q to be HIGH ( 3:10) with either of the inputs to that NOR gate also being HIGH. This video has been out for nearly three years and no one has noticed this?

I think you've got Q and Q bar reversed on your SR flip-flop. Looking at the top NOR gate, if either of its inputs is high, the output will be low, meaning that if SET goes high, Q will go low. Edit: it turns out the more common way is to switch RESET and SET, but the end result is the same.

Very nice instruction but I am confused. How is it possible that the flip flop examples (time 2:42) show both gates with set and reset inputs connected together denoted as ground, and that independently each input is said to be at different states, either high while the other is low or vise a versa?
@DiffEQ
2 жыл бұрын
This is an undefined state and the example should not be shown this way. It's confusing. It's also incorrect. If you were to power up the flip-flop with both inputs tied low, then it's simply a race condition as shown and you do not know if Q or Q-NOT will be HIGH. Circuitry in modern flip-flops can be implemented to prevent this unknow initialization state, but typically a master SET or RESET is generated because the STATE of system must be DETERMINISTIC and the only occurs if the STATE is predictable. The example for the active-high RS is incorrect. Either the SET and RESET need to be swapped or the Q and Q-NOT need to be swapped. It is IMPERATIVE when making instructional videos to be accurate or it will just confuse the viewer. How does anyone , in the know, miss that the output of a NOR gate cannot be HIGH if either of the inputs is HIGH? (3:10)

She's got it the other way around but she still continues the description of the circuit as if the inputs and outputs are named in the usual way (if you swap the outputs together with their values, they go back to being correct). Hence the values are all wrong. E.g. at 3:07, with S = 1 then Q must be 0 Same error at 4:44 with S = 1. again Q must be 0 in the circuit on the left (the one called "Active High").

Your pretty. Very pretty. But although I am a little worried of my being a little stubborn I encourage you to imagine Gates , Latches , and Flip Flops of every sort being made with only SPSD relays which shows everything involved in an easy to understand manner (unless you state what beneficial end the circuits shown have. Such as using fewer components by doing something like adding a circuit that resets all the RS flip flops at power up.) I hope I don't sound like I am being mean when my objective includes being helpful . By starting with the simple relay logic method everything can be seen with the eyes as switches in one of two positions depending on whether an electromagnet is on or off. From there following the rules for the type of ICs used will allow the circuits to be converted from one method to the other.

This series is great because you're using visuals to such great effect ! So easy to see what you're explaining, because up until recent times, we had to memorise what was illustrated in voluminous text books ! And you're explaining it so clearly to us ! This series is so useful because we can bookmark it and return as often as we need to for a refresher ! An Arduino makes things too easy; in a way it is a sledge-hammer to crack a nut, whereas we can ( and did ) use a flip flop to do the same job much more simply. As I said in another comment. this was the way that computers were built - they lived in air-conditioned rooms the size of Walmart, with hundreds of flip-flop boards each using 3 transistors. Because computers can't stop if they're multi-programming, the data has to keep cycling round until it is needed, which it did in these rings of flip flops ! Things began to change in the mid 1970s, when integrated circuits took over from discrete transistors for flip flops, and the shrinkage in hardware size began to take off. IT's great that you're covering all of this in this series - thanks !
