Evaluate the form factor:
For the saw tooth wave illustrated in Figure, find out the form factor.
Figure: Saw Tooth Wave
Solution
Time period of given wave is 2 sec. Expression of function f (t) for first time period.
f (t ) = (10/2) t = 5 t for 0 ≤ t ≤ 2
RMS Value
Form Factor
K _{f} = F_{rms} / F_{av} = 5.77/5 = 1.154 .
