# Bandwidth of a composite signal

How to find bandwidth of a composite signal that can be decomposed into five sine waves with given frequencies and having all peak amplitudes same ?

• Unless I'm missing something here it would just be the difference in frequency between the highest frequency sine wave and the lowest? Oct 14 '13 at 11:39
• @PaulR You have more votes than either answer - might as well make yours one as well. Jul 22 '14 at 12:17
• @DavidK: sure - consider it done! Jul 22 '14 at 12:50

BW = Fmax - Fmin
