Without your videos, I would be questioning my future as an EE major because of how hard my professor makes the material seem. You manage to make everything seem like common sense especially when you try to relate to real world examples. The world and more specifically the realm of teaching needs more people like you. For this, I thank you.

I appreciate this lecture. Having designed switching systems in industry, this is a great refresh/reinforcement of the basic principles upon which many systems act, with either an active high or active low Set/Reset channel switch, be it fiberoptic, ethernet, etc. It is great to see that it is also completely done in the computer, as opposed to the traditional chalk/whiteboard. Many thanks, Jim,for your time & for making this freely available to all!

Those who liked this video...you guys are not study enough....Jim definitely did a great job on the explanation, but there are two other very basic tables beside the timing diagram which depict the relation between the change of state and output. Where are the two tables?

@baharsahin Hi I'm French, There is no differences, you just invert the position of R and S (R in front of Q and S in front of Q prime). You start with S,R = {0,0} and you read the NOR's truth table (only 0,0 makes 1). The set and the reset have the same impact to Q. Actually, the NOR's truth table is the same than NAND's one if you change 0 to 1, and 1 to 0.

I guess it's because just using 2 NOR gates will be cheaper than using 2 NOT and 2 NAND gates. Even though a NAND gate in the IC can be used to implement a NOT gate function to substitute an actual NOT gate, ultimately still using only one NAND IC chip, 3 gates will have to be used in one IC, as opposed to only 2 if using NOR implementation.

Thanks for not assuming everyone would immediately understand what latch would mean. Question. I have a small dc motor, which when the polarities are reversed, the rotation of the motor reverses, which is what I want. Is a flip flop the best way to control the reversal of polarities? Does 0 equal ground? Thanks!

sooooo.....at power up, some sort of delay to the "set" must be implemented so that reset in high first to guarantee "Q" is at logic "1" or is there some sort of built-in system for this.

In my book, it uses NOR gates instead of NAND gates. What is the difference between using NAND gates and using NOR gates in SR latch?
@TheMo0

You said that when you hit Set AND Reset at the same time, you get an unpredictable Q output. Does this mean you can create a RANDOM bit of data? Maybe not *truly* random, but at the least, very unpredictable?

what kind of drawing program are you using. I am in EET 121 and we are going over latches this week. it was confusing me if you just have one input on a two input gate it will not work. So you have to start with initial conditions, otherwise it will not work. otherwise you cannot get any output to Q ever. the gates will never work unless you have initial conditions
@shikhanshu

but how do you enforce that initial "set" condition where Q=1 and Q'=0? how can you drive the outputs to something?

***** This is probably a bit late for this comment, but he didn't really "derive" the Q=1 and Q'=0 from anywhere, it was a given variable. He didn't really show that it was a given in the first example but he did in the second one with the timing diagram.

So an SR Latch is always an active low? and i know when in set mode Q = 1 and reset mode Q = 0 but does that also mean that S = 0 for set? and R = 1 for reset?
@italianbasegard
9 жыл бұрын
Because this is the NAND version of the SR Latch (instead of the NOR version) it uses S-bar (not S) and R-bar (not R). S = 1 is still set, causing an active low of Sbar (not S) = 0. R = 1 is still reset as well, causing Rbar (not R) = 0
