# Finding the Period of a Signal by Its DTFT Data

find period of DTFTs where vertical lines represent Dirac deltas

• are you in the same course as praneeth bharath? His question contains a screenshot of seemingly the same workbook.  our problem with both questions is the same: we really can't help you if you're not even showing what you've tried so far, and where you've got stuck. You need to ask your own specific question! – Marcus Müller Jul 5 '18 at 9:48
