Answers to Common Questions
( ′näch ′fil·tər ) (electronics) A band-rejection filter that produces a sharp notch in the frequency response curve of a system; used in television transmitters to provide attenuation at the low-frequency end of the channel, to prevent pos...
A passive circuit fed from a 32 ohm source impedance and loaded with a 32 ohm load that consists of a 2.5 mH inductor in series with a 10 uF capacitor, this series network is placed between the signal and ground will give you a 1KHz notch t...
I think that actually even having a filter makes this an actual issue. If someone goes around dropping the f-bomb on a modded forum, he will be called out by the more adult crowd, "Calm down bro". In a filtered forum this is block...

garycase is correct for ideal filters, and he is may be correct for some real filters. A real-band pass filter can not completely remove frequencies in its stop band, only attenuate them. You would have to look at the filter design and spec...

I can confirm that the 4 behind a 2 does not work. I tried this before and my CM would not work. I guess my solution is going to be an amplified system. I have 2 primary concerns. 1) The cam signal stays in the house 2) CM keeps working. An...

No. There is no need for notch filtering with the Bortec AMT-8, or any other system using differential pre-amplification of the EMG signal. Differential pre-amplification allows for the rejection of 50Hz or 60Hz hum (power-line noise) and o...
