Improved RS-Latch

01:21:55

Improved RS-Latch from the last one.
This version will remove the bounce that occurs in the real world. It cannot be shown with this simulator. 

Further Reading: http://en.m.wikipedia.org/wiki/Switch#Contact_bounce

·Active-HIGH Input RS Latch.

Outputs by LED Color:
Red=Q
Purple=NOT-Q

To Operate: 
The SPDT switch alternates between SET and RESET. 

Comments, criticism, questions are welcome.

You're almost right. This is a de-bounce circuit, but only (as it is) a de-bounce. It isn't a RS, which is apparent by it's inability to perform the RS function. Try combining this circuit with your recent (working) RS latch, by replacing the SPDT switches of the other circuit with Q and NotQ of this one. You follow?..

Whoops! Sorry, scratch that last idea (sort of). I briefly forgot that a de-bounce circuit is intended to replace only one switch. So, maybe I think 2x de-bounce ---> RS Latch will work.. X^)

Hmmm alright I'll modify this to try and correct it. Thank you!

Hmmm perhaps you could make an example so I can understand a bit better. I've attempted to do so myself and cannot seem to grasp what you are referring to. In advance thank you!

Ask, and you shall receive. I worked up a circuit for ya- and posting it now...
