Abstract :
This correspondence shows quantitatively why the narrowband low-pass to band-pass frequency transformation has such surprisingly good delay-preserving properties for wide bandwidths. Also presented are easily computed approximations to the low-pass delay at high frequencies and to the relative delay error at band center due to the transformation.
