[QUOTE="Timo Beckman, post: 65098, member: 1173"] Re: Visualizing the Mag & Phase of the 2 Element "End-Fire" Sub Array I do know and every now and than i get the question from the people that hire me about fir filters (today was 1 of those days ;-). I know a bit about how the fir thing works but i tell them i'm not messing with them for a lot of reasons but the main reasons being : 1st : i'm not a mathematician so i do not know how to develope a fir filter and 2nd : i can't controll them or change them in the field if needed . The method i'm using to correct or better change the phase respons of a system is via a combination of delay all-pass filters and different combinations high and low-pass filters . It adds a bit of latency to the system (so does FIR) but it's something i understand (a little bit thanxs to the meyer sound educational program and specialy MAGU and Bob) and it's something i can controll live in the field and alter real time wich works better for me . I would still like to know how to develope a fir filter but i think it will take me a long time to really understand the tech stuff involved but maybe who knows where i'll be within say 5 years .....
