Question

A pulse waveform has a high time of 8 ms and a pulse width of 32 ms. The duty cycle is

• A. 25%
• B. 50%
• C. 1%
• D. 100%

Answer 1

The correct option is A 25%

Given: A pulse waveform has a high time of 8 ms and a pulse width of 32 ms

To find the duty cycle

Solution:

According to the given criteria,

Rise time = $8ms$

Total time period = $32ms$

The formula used is

$\text{duty cycle}=\frac{\text{Rise Time}}{\text{Total time period}}\times 100$

$⟹\text{Duty Cycle}=\frac{8}{32}\times 100=25\%$

is the duty cycle
