I was wondering , what's the best method to provide interrupt for a level triggered circuit ?

A) A switch
B) A function generator?

What do you is a better choice ?

 

Hello,

A switch will need debouncing.(otherwise the level wil flip some times before a stredy state is reached).
A function generator will probably be giving more pulses set by the repetition rate.

debouncing is related to relay circuits not state of the art circuits. there are many cmos ttl switches that you can use even trystate your choises.
