solved:a. A sinewave has a period (duration of one cycle) of 645

  

a. A sinewave has a period (duration of one cycle) of 645 s. Whatis the corresponding frequency of this sinewave, in kHz, expressed to 3 significant figures? (See Study Note 7.1 in the ‘Using Numbers (maths)’ booklet.)A (I) If the frequency of the sinewave is now reduced by a factor of 3.5, what will be the new period value? Express your answer in ms, to 3 significant figures.Note: In the second part of this question, to avoid rounding errors in your calculations, use the full frequency value from the first part, not the rounded value to 3 significant figures.Computer ScienceEngineering & TechnologyNetworking
