Question

What is the frequency, in units of kiloHertz, of an AC waveform that has a period of 12 microseconds?

Answer 1

83.3 kHz

Step-by-step explanation:

The frequency of a waveform is equal to the reciprocal of its period:

`f=(1)/(T)`

where

f is the frequency

T is the period

In this problem, we have

`T=12 \mu s=12\cdot 10^(-6) s`

so, the frequency of the waveform is

`f=(1)/(12 \cdot 10^(-6) s)=8.33\cdot 10^4 Hz`

And by converting into kiloHertz,

`f=8.33\cdot 10^4 Hz=83.3 kHz`
