Re: Interpolating FIR Filter - sample delay

2022-04-25 Thread Daniel Estévez
Hi Marcin, What I mean is that currently we need to entering group_delay // interpolation_factor in the Sample Delay field. And that number needs to be an integer. So unless group_delay is divisible by interpolation_factor we won't get exactly the correct delay in the output (just consider

Hi Daniel, Thank you for your detailed response. Indeed, that's what I do now is to set the Sample Delay equal to: filter group delay divided by an interpolation factor. One thing I don't understand in your response is: *"However, I don't think this is a very good solution, because it forces*
