Digital Concepts - Technical MCQs

Q1:

In a certain digital waveform, the period is four times the pulse width. The duty cycle is ________.

A 0%

B 25%

C 50%

D 100%

ANS:B - 25%

Here,
The time period is given as 4 times of pulse width.
Duty cycle= on time(positive pulse width)/((on time + off time)(i.e.Time Period)) *100.
Let P be the period.
So Duty cycle%= (P/4P)*100= 25%.
