The low-pass filter consists of a resistor and capacitor wired as shown. The reactance of the capacitor is low at high frequencies and thus it shunts high frequency signals from the speaker. Again, one may think of the circuit as a voltage divider. Since X C = 1/ωC and Z = √ (R 2 +X C2 ), V in /V out = 0.85 at 100 Hz and 0.16 at 1000 Hz.

The passive low-pass filter allows all frequencies lower than the cut-off frequency to pass but attenuates those higher than the cut-off. These filters do not have a bandwidth limitation and require no power source to operate. They’re typically used to drive low-frequency elements of an audio signal to a woofer.

Applications of passive Low Pass Filters are in audio amplifiers and speaker systems to direct the lower frequency bass signals to the larger bass speakers or to reduce any high frequency noise or “hiss” type distortion. When used like this in audio applications the low pass filter is sometimes called a “high-cut”, or “treble cut” filter.

Low-pass filters always transition smoothly from the passband to the stopband. Furthermore, there is nothing magical about the “cutoff” frequency, which is more accurately referred to as the –3dB frequency, i.e., the frequency at which the magnitude response …
