Microchip Technology Applications Engineer Interview Questions and Answers

Q1. Can make a simple button debounce circuit ?
Ans. 
Yes, a simple button debounce circuit can be created using a resistor and a capacitor.
• Use a resistor and a capacitor in series with the button to create a low-pass filter.

• Connect the output of the filter to a Schmitt trigger to clean up the signal.

• Adjust the values of the resistor and capacitor to achieve the desired debounce time.

• Example: Use a 10k ohm resistor and a 0.1uF capacitor for a debounce time of 10ms.

Q2. What is physical significance of 2nd order on filtwrs
Ans. 
Second order filters have steeper roll-off and better attenuation of higher frequencies.
• Second order filters have a slope of -40 dB/decade.

• They have a higher Q factor than first order filters.

• They provide better attenuation of higher frequencies.

• Examples include Butterworth, Chebyshev, and Bessel filters.
