regarding sweep generator

Started by abhi...@wipro.com January 16, 2006
hello

i am facing one problem regarding the sweep waves generation from the sine generator.
actually the sweep waves are continous sine wave with varing frequencies.

but the problem is when the frequency changes the amplitude also changes.

i am doing asm coding on the 21365 ADSP sharc processor.

please help me out from this one.

thanks
abhishek

Do you have a filter section that shouldn't be on, but is?

Otherwise, there shouldn't be a gain change.
