Hi Guys
I know that if you have a main DB feeding a 2nd DB, then the Ze for the 2nd DB is:
Zdb = Ze from origin + (r1 +r2) of the cable supplying the 2nd DB. Or measured Zs at the second boards supply. But how do you then get Ze for, say a 3rd DB fed from the 2nd and then Ze for a 4th DB fed from the 3rd etc?
Any advice would be appriciated
