Question

If the period of a signal is 1000 ms, then what is its frequency in kiliohertz?

• A. $10^{-3}$ KHz
• B. $10^{-2}$ KHz
• C. $10^{-1}$ KHz
• D. 1 KHz

Comments

option (A) 10^-3 khz

Answer 1

f=1/t

t=1000ms=1sec

f=1/1sec=1000/1000s=1K/1000s=

10−310^-3 KHz10−10^−3 KHz

Answer 2

Frequency = 1/Period.
      So frequency = 1 / 1000 x 10^-3 Hz
                    = 1 Hz
                    =  10^-3 KHz
