Question

The period of a signal is 200ms. What is its frequency in Megahertz(MHz)?

Answer 1

0.000005 MHz

Step-by-step explanation:

The time period of a signal is 200ms

=> T= 200ms = 200×10^(-3)s

Frequency of a signal is given by

f = 1/T

=>f = 1/(200×10^(-3))s

=> f = (1/200) × 10³ Hz

=> f = 5×10^(-3) × 10³ Hz

=> f = 5 Hz

To get the frequency in Megahertz, we have to divide the frequency in Hertz by 10⁶.

So f = 5/10⁶ = 1/200000 = 0.000005 MHz (Ans)
