Low pass filters
Low-pass filters are electronic circuits that allow low-frequency signals to pass through while attenuating or blocking higher-frequency signals. They are commonly used in audio systems to remove high-frequency noise or to limit the bandwidth of a signal. Low-pass filters work by using a combination of resistors, capacitors, and inductors to create a frequency-dependent impedance. This impedance causes the filter to selectively pass low-frequency signals while attenuating higher-frequency signals. The cutoff frequency of a low pass filter is the point at which the filter begins to attenuate the signal. Different types of low-pass filters, such as Butterworth, Chebyshev, and Bessel filters, have different characteristics and are used in different applications depending on the desired freque...
