Low pass filters are the polar opposites of high pass filters. They allow frequencies below a certain cutoff point to pass while attenuating higher frequencies. In digital music production, a low pass filter is great for isolating the low-end elements like basslines and kick drums.

The low-pass filter section is comprised of R 1, R 2, and C 1 in a “T” configuration. The high-pass filter section is comprised of C 2, C 3, and R 3 in a “T” configuration as well. Together, this arrangement is commonly known as a “Twin-T” filter, giving sharp response when the component values are chosen in the following ratios:

Summary. The main difference between a low pass and high pass filter is that the low pass filter circuit passes frequencies lower than the cut off frequency while the high pass filter passes frequencies higher than the cut off frequency. Both low pass and high pass filters use a resistor and a capacitor, but the orientation in each is reversed.SNAP.
