[QUOTE="Timo Beckman, post: 65004, member: 1173"] Re: Visualizing the Mag & Phase of the 2 Element "End-Fire" Sub Array I do regognize the graph's . The top blue is the "reverse comb filter" respons a gradient sub array has @ the audiance side and the red might be the respons of a end fired 2 element array @ the stage side . The bottum screen looks to me like the respons you try to get at the stage side of a gradient array . I'm completely lost however on the math in the screenshot but that's my bad : i'm not in to the math formula's that apply to these array's . I'm just using the data measuring real live arrays with SIM3/SMAART/SAT-live . The frequency respons is simular when using MAP on Line and the RBV2-9 program . @ my blog i did some posts about these [SIZE=2]arrays [/SIZE][URL="http://timobeckmangeluid.wordpress.com/2011/11/08/end-fired-sub-array-only-in-english/"][COLOR=#000000]http://timobeckmangeluid.wordpress.com/2011/11/08/end-fired-sub-array-only-in-english/[/COLOR][/URL][URL="http://timobeckmangeluid.wordpress.com/2011/11/14/the-gradient-sub-array-or-reversed-end-fired-as-i-call-it-english-only/"][COLOR=#000000]http://timobeckmangeluid.wordpress.com/2011/11/14/the-gradient-sub-array-or-reversed-end-fired-as-i-call-it-english-only/[/COLOR][/URL] [URL="http://timobeckmangeluid.wordpress.com/2011/11/16/csa-the-cardioid-sub-array-according-to-some-from-db/"][COLOR=#000000]http://timobeckmangeluid.wordpress.com/2011/11/16/csa-the-cardioid-sub-array-according-to-some-from-db/[/COLOR][/URL] [URL="http://timobeckmangeluid.wordpress.com/2011/11/18/why-even-bother/"][COLOR=#000000]http://timobeckmangeluid.wordpress.com/2011/11/18/why-even-bother/[/COLOR][/URL][COLOR=#000000] The problem i ran in to was of axis response and the way to do calculations on the level wich again is due to me not paying attention during high school math & physics so i decided to stick with the data on screen of my measurement devices in real live situations .
