Frequency and period of signal - Computer System Architecture

Question 1 UGC NET June-2020
The period of a signal is 100ms. then the frequency of this signal in kilohertz is __?

A – 10

B – 10^-1

C – 10^-2

D – 10^-3

Show Answer With Best Explanation

Answer : c
Explanation:
Period = 100 ms = 100*10^-3 = 10^-1s
Frequency = 1 / period = 1 / 100 *10^-3
= (1 / 10^-1) Hz
= (1 /10^-1 * 103) KHz
= 1 / 10^-2 KHz
=10^-2KHz
