 		 #175145 - Not talking on rogowski coil
Responding to: ???'s previous message
Thanks Andy Neil for your reply.

I am not talking about rogowski coil.But now I'm studying on signal processing. I would like to design a butterworth LPF with a cut off frequency of 20Hz,thats what I meant. Why because I am dealing with low ferqunecy signal which is in the range of 40 - 80 Hz.

   You need to be more specific            01/01/70 00:00      
      "Buffer" can be used in several contexts            01/01/70 00:00      
         So it is an input buffer for impedance matching            01/01/70 00:00      
            You really should ask the one who said it!            01/01/70 00:00      
               Does it mean that the delay matching buffer not required            01/01/70 00:00

      Then put a filter in front of it!            01/01/70 00:00      
      So you're amplifying the noise?!            01/01/70 00:00
