![]() ![]() Low-pass filters are used for conditioning signals prior to analog-to-digital conversion and are called anti-aliasing filters. Those who use ADSL Internet connection have these filters installed in DSL splitters that prevent interference between telephones and DSL equipment connected to the telephone line. ![]() They are also used in radio transmitters to block unwanted harmonic emissions. One example is using them in subwoofers to block high frequencies that they cannot reproduce. Such filters are widely used in electronics. The cutoff frequency is determined by the components in the filter circuit. Low-pass filters pass only low-frequency signals and attenuate high-frequency signals. An example of a second-order two-stage RC low-pass filter with a non-inverting unity amplifier, which is used as a buffer between the two filter stages. ![]()
