Webb2 nov. 2013 · I simulated the low pass filter tonight (LTspice) using the values of 7.9 uH and 15 uF suggested from some of the online lowpass filter calculators. From the simulation I see 0 dB in most of the passband but then I see a huge resonance point of +32 dB at 14.49 kHz! Here is a link to the simulation result: WebbThis type of trade-off exists in image scaling as well as audio filtering, if that's more familiar to you. There's also the linear phase filters, which have a symmetrical impulse response, and the minimum phase ones, which have no pre ringing. The linear filters have no group delay (all frequencies have the same delay), so that is considered good. simple one electric scooter in goaWebbA lowpass filter used for that purpose is called an anti-aliasing filter.

"Many digital filters are designed to give low-pass characteristics. Both infinite impulse response and finite impulse response low pass filters as well as filters using Fourier transforms are widely used. The effect of an infinite impulse response low-pass filter can be simulated on a computer by analyzing an RC filter's behavior in the time domain, and then discr… " - Sharp low pass filter digital
