Help me design a low delay filters for signal at 10MHz

[bizoo]

Hi guys

i wana design a filtering technique to remove the noise from my signal whose modulated at 10MHz and thus will be sampled to atleasst 20M samples per seocnd


Current SNR is around 10 and i want to improve the signal quality so to have a better recnostruction
the problem is that i want a low order filter because my system is real time and so is delay sensitive,
so anyt help on designing a low delay filter in my case or in general will be appreciated to say the least

Re: Low delay filters

First thing is that you dont need to have a sampling rate of 20MHz for a bandpass signal with carrier frequency of 10MHz! This is a common mis-understanding, the Nyquist theorem states the sampling rate has tobe equal or greater than the signal bandwidth. You may need to look into bandpass sampling theorem.
