How to solve comparator noise problems with hysteresis

Learn more about the TI Precision Labs - Op Amp Evaluation Module used in the hands-on lab modules

In this video we will introduce how external noise can affect a
comparator’s basic function. We will then discuss the concept of hysteresis
and how it can be used to solve noise problems, including how to select
component values to achieve different levels of hysteresis.

Man, this just made so many things make sense to me that I have just been following formulae for without knowing why >:)

Nice video

Good old days!

[@shubhamingle6137]

how R1 and R2 are parallel while calculating the R3.........?

[@sergioalejandrogonzalez9755]

This is NOT mandatory; is just common practice to maintain input bias balance in the comparator. Cheers.
