Hi , I am new in here. I have a question :I calculated single end( point to point) Z is 65 ohm (with Impedance calculator that I have) and the software has also a option where i could calculate bused trace.I calculated bused impedance with same parameters but I got 57.8 ohm insatead of 65 ohm. could any body will explain me why bused trace impedance is reduced .please if it possible give me reference where i could get this info. thanks for advance. regrads taskina __________________________________ Do you Yahoo!?
