Here's the question bank on all the computer networks topics.
period of a signal is 100 ms. Then the frequency The of this signal in kilohertz is ______.
Data:Period = T = 100 msFormula:\({\rm{Frequency\;f}} = \frac{1}{{\rm{T}}}{\rm{\;}}\)Calculation: \({\rm{f}} = \frac{1}{{100{\rm{\;ms}}}} = \frac{1}{{100 × {{10}^{ - 3}}{\rm{s}}}} = 10{\rm{\;}}{{\rm{s}}^{ - 1}} = 10{\rm{\;Hertz}}\)f = 10 × 10-3 kilohertz = 10-2 kilohertz
