Hello everyone,
I am trying to make a passive low pass filter for a speaker. I have some .15mH coils. I put two of them in series and tested it on my inductor tester and it reads 303:mu: H. Which is .303 mH correct? So i put that in series with an 8
hm: speaker, hooked up my signal generator and mt scope to the speaker. The problem is i don't see any change in amplitude whatsoever all the way up past 10kHz. I figure it should drop of at 4kHz. Any ideas as to what could be going wrong?
