suppose i have 4 nodes (N1,N2,N3,N4) and 2 ac source (both same magnitude ~1v and 180 deg phase shifted, 10khz ).
now suppose out of these 4 , two of them are are connected to ac source(one to each source using same circuit, same component) in the pcb itself, now the other two node i connected to the sources using normal wire but am seeing higher noise on these nodes , some pickup should be there because of this , but is there any way to quantize how much more will it be, also suppose if in the new board all the 4 nodes connection is made in the pcb itself will that help?
