FFT Windowing

#1 Post by lpmsr » 05 Sep 2009 15:58

Does anyone have any proven window functions that they have implemented in MB? I have tried a couple different windows ahead of FFT, and they definitely improve leakage, but none have had enough dynamic range or resolution to make an acceptable display when using a log scale. I am seeing about 35dB dynamic range between maximum signal and noise floor.

Thanks for the feedback. I sent something to the support desk last week, but haven't heard back yet. Would it make sense to also post my message to the MikroPascal and MikroC dsPIC forums? Is there one forum where general dsPIC topics are discussed?
