Size problem after filtering

1 次查看(过去 30 天)
Hi,
I have filtered my signal of size (n), with a filter of size (NFFT). After filtering, my new signal have a length of NFFT. Is it possible to recover the initial length (by downsampling or resampling) ?
Thank you,

This happens because it only samples at the size of the NFFT. You could resample your data with the
resample
function.
