Question

Given the following frequencies, calculate the corresponding periods. a. 60 Hz b. 8 MHz c. 140 kHz d. 2.4 GHz

Answer 1

The frequency can be defined as the inverse of the period, that is, it can be expressed as

$T = \frac{1}{f}$

Here,

T = Period

f = Frequency

For each value we only need to replace the value and do the calculation:

PART A)

$T = \frac{1}{f}$

$T = \frac{1}{60Hz}$

T = 0.0166s

PART B)

$T = \frac{1}{f}$

$T = \frac{1}{8*10^6}$

$T = 1.25*10^{-7} s$

PART C)

$T = \frac{1}{f}$

$T = \frac{1}{140*10^{3}}$

$T = 7.14*10^{-6}s$

PART D)

$T = \frac{1}{f}$

$T = \frac{1}{2.4*10^{9}}$

$T = 4.166*10^{-10}s$
