How Does a Low Pass Filter Work?

Answer

An electronic filter known as a low pass filter works to pass low frequency signals while reducing amplitude of frequencies. They can be used in electronic circuits, digital filters, and other applications that call for a smooth signal. The low pass filter can help in audio by blocking high pitched sound, block harmonic emissions, reduce treble in the sound of an instrument, and to eliminate all frequencies that fall above the cutoff frequency in an electrical or audio flow.
