If you detect power failure by monitoring a voltage level, you have to make more than one observation to detect that the voltage is dropping.

(a) True

(b) False

The question was asked by my college director while I was bunking the class.

My query is from Embedded Software in portion Advanced Software Engineering of Software Engineering

Answer 1

The correct choice is (a) True

To explain I would say: If you run the process 250 times per second, this means that it runs every 4 ms and you may require up to two periods to detect the voltage drop.
