I'm trying to implement an RC debouncing circuit into a design I'm currently working on, and I have been using this PDF as a reference: <https://my.eng.utah.edu/%7Ecs5780/debouncing.pdf>

In the PDF, the math is described on how to obtain values for R2 and C. I want to account for a button that has about 10ms of noise, so using the formula in the PDF I get that my values for R1, R2, and C should be

* R1 = 10Kohm
* R2 = 160Kohm
* C = 0.1 uF

The Schmitt Trigger inverter that I plan to use is the 74HC14D. Its datasheet is found here: <https://www.nexperia.com/products/analog-logic-ics/asynchronous-interface-logic/buffers-inverters-drivers/74HC14D.html>

And the following circuit setup is from the PDF as well:

However looking around, I find that there are people similar to me who also want to implement a debouncing circuit for their buttons as well. Most of the time, I am finding that the following values for R1 and R2 and C work as well:

* R1 = 10Kohm
* R2 = 10Kohm
* C = 0.1 uF

The only difference between my values and the above is that my R2 is really high. Looking around on the EE stack exchange, I've also found that R2 should not be too high, or else the voltage at point A on the diagram will not be low enough for the inverter to register the voltage as LOW. Do I trust my calculations, or have I incorrectly done my calculations somewhere along the way/misinterpreted the PDF?
