Question

The period of a signal is 100 ms. Its frequency is _________. (1) 1003 hertz (2) 102 khz (3) 103 khz (4) 105 hertz

Answer 1

Period (T)=1/f
f=1/T
f=1/100
f=0.01Hz

Answer 2

Given :

The period of a signal is 100 ms .

To Find :

The frequency of signal .

Solution :

We know , 1000 ms = 1 s .

We know , frequency is given by :

$f=\dfrac{1}{T}\\\\f=\dfrac{10}{1000\ ms}\\\\f=10\ Hz\\\\f=10\times 10^{-3}\ kHz\\\\f=10^{-2}\ kHz$

Therefore , the frequency is $10^{-2}\ kHz$ .
