Appendix A. General Principles of Pulse and Frequency Measurements

A-4

The relationship between the minimum debounce time in milliseconds (t

d

) and

the debounce parameter (n) is:

t

d

= 0.244 + n * 0.244

The relationship between maximum frequency (f

max

), debounce time and total

switch bounce time (t

b

) in milliseconds is:

f

max

= 1000 / (2 * (t

d

+ 2 * t

b

))
