• downsampling by a fraction

    From Mike Sousa@21:1/5 to All on Fri Jul 14 09:05:33 2023
    Hi

    I need to downsample an image (bitmap image of a Spectrogram) by a fraction, N/D, (rational: ex 4/5). I understand that this can be done with resampling by 4 followed by decimation by 5. If this is true, is there a more efficient way in this case, more
    efficient == computationally faster)?
    Thanks...
