No, the decimation is applied to FFT *output* frames, after integration. It is typically the case that in radio astronomy spectrometry that you integrate spectra over some time period, since the SNR is typically quite poor.Hi, I have a question regarding the block RA:FFT in the RA Blocks package.If I set, for example, the decimation at 100 does this mean that only 1 in 100 items will be kept? In that case it would occur to me if, I do say a measurement of 100 minutes at a signal, I only get 1 minute of data?Best regards Simon _______________________________________________ Discuss-gnuradio mailing list address@hidden https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
