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 C 2), V in /V out = 0.85 at 100 Hz and 0.16 at 1000 Hz.

Despite being overall a “low-pass” system (filtering out the higher-frequency harmonics), this band-stop filter still employs capacitors to define the upper limit of the blocked frequency band. Capacitors can be found in every sort of electronics we use, from guitar amps to your car’s starter to the surge protector your computer is plugged into right now.

The constant is typically on the order of .01 or less, and varies with the line of capacitor. For audio purposes, we don’t care how much leakage occurs when the amp is turned off. It can be significant for filter capacitors, however. Leakage current is proportional to the capacitance and voltage, and filter capacitors have a lot of both.

The actual low-cut filtering is accomplished by the 0.1 uF. capacitors in conjunction with the 390 ohm resistors. Amplifiers A2 and A3 are also used for isolation, but in this case when coming out of the filters. Automatic operation is realized by the 2N5457 FET's voltage-controlled resistance.

A filter capacitor is a capacitor which filters out a certain frequency or range of frequencies from a circuit. Usually capacitors filter out very low frequency signals. These are signals that are very close to 0Hz in frequency value. These are also referred to as DC signals.

Filter capacitors in the broader sense are used in all sorts of filters used in signal processing. An example application is an audio equalizer, which uses several frequency bands in order to allow different amounts of amplification for bass, midrange and high frequency tones. Energy Storage.
