How to make a low pass filter
Did you know?
WebBand-pass filters can be made by stacking a low-pass filter on the end of a high-pass filter, or vice versa. “Attenuate” means to reduce or diminish in amplitude. When you turn down the volume control on your stereo, you are “attenuating” the signal being sent to the speakers.

WebYou can use a digi-pot to make the resistor variable. Then select multiple capacitors that have values that define the filter ranges that work with the resistance range of the digi-pot. Use an analogue mux chip to select which capacitor is switched into the filter circuit at any given time. Deploy a microcontroller to control the pot and mux. WebJun 19, 2010 · Just simple one so that only low frequencies can be heard. A single pole (=6dB/oct = 20dB/dec) will let through a lot of intelligible upper frequencies. A 2pole will let through less but still hearing too much of the midrange. A 3pole may be satisfactory, but I would recommend a 4pole low pass filter. A simple circuit of just a R+C can only ...
