Digital debouncer ? choose the purpose. Use this to support: Calculate resonant frequency where appropriate.
- A.digital debouncer: the circuit prevents rapid false logic changes from switch bounce for LC resonance filters.
- B.digital debouncer: uses carrier modulation.
- C.digital debouncer: claims it increases analogue gain.
- D.digital debouncer: ignores repeated contact changes.
Model answer
What a good answer should say
- The correct option is digital debouncer: the circuit prevents rapid false logic changes from switch bounce for LC resonance filters.
Explanation
Why this works
This is the best answer because the digital debouncer context requires that exact electronics relationship. The other options are incorrect because they use a different component, reverse the circuit behaviour, or omit the output interpretation required for LC resonance filters.
