simple FFT for cortex m0
Problems addressed by these changes: - Output of ZeroFFT function is scaled down by a factor of two. - Results of ZeroFFT function are the real portion of the complex...
While trying out this library, I found something strange with the behavior of the `ZERO_FFT_MAX` value. While I am using this library with a Raspberry Pi Pico instead of an...
Hi all. Been really enjoying your products and supporting libs. I am a but new to C/++ code and am trying to override the ZERO_FFT_MAX define in the header. It...
This changes the output of the function to return the value users would expect from an FFT, it's magnitude. The previous behavior was to discard the imaginary data, which can...
Hello, Thank you for the usefull library! i'm using your FFT library to realize a spectrum analyzer. For testing i connect a 150mVpp sinusoidal wave with a 500mV DC value...
The hanning window function is useful when there is a chance of leakage in the FFT results for some scenarios with periodic signals. However, windows aren't always the best approach...
