If you study a DC signal under an appropriate scope, you can see the switching transitions ; a pwm signal.
But if you examine a battery, no matter how high temporal resolution you reach, you see a dc signal.
What might be the explaination for this? electrons are being generated by a chemical process in battery and these reactions are very fast so the switching frequency of battery can be very high. What should be the approach to this problem?
