Hello All,
Can someone suggest me which of the following two designs is better and why?
I have 4 signals in the following configuration for each-
I/Pi -> NI-Bufferi -> LPFi -> I-Gaini -> O/Pi where i=1to4
Now if I want to add them together (summing) is it better to sum them after their LPFs or is it better to sum them before and then pass through an LPF?
Lets say I select CH1 as master, so if I decide to sum all 4, is the below configuration better?
I/Pi -> NI_Bufferi -> I-Summing1 -> LPF1 -> I-Gain1 -> O/P1
or
I/Pi -> NI-Bufferi -> LPFi -> I-Summing1 -> O/P1
NI = Non-Inverting, I = Inverting.
Any ideas/suggestions are greatly appreciated.
thanks.
