FIlter out any signal higher than 100k Hz
Please clarify. Is 100 kHz your 3db point (cut-off)? Or are you saying that the signals above 100 kHz are "completely" gone?FIlter out any signal higher than 100k Hz
im trying to feed it to a ADC converter. is there a chip that i can use?What does the output feed?
If you are feeding the input of an ADC (or another high impedance load) why not just use a RC filter configured as a low pass?
That has a 3dB cutoff frequency of 284Hz, and drops at 6dB per octave.You dont need a chip all you need is a resistor and a capacitor.
This circuit will give ayou a cut off point of about 1K and a drop of about 3db per octave.
