For the 5120 point FFT, can we downsample it by a factor of 5 to 1024 points? and then interpolate the FFT to get the 5120 points? | For the 5120 point FFT, can we downsample it by a factor of 5 to 1024 points? and then interpolate the FFT to get the 5120 points? | ||

For the 5120 point FFT, can we downsample it by a factor of 5 to 1024 points? and then interpolate the FFT to get the 5120 points?
