WebAn example of an analogue electronic band-pass filter is an RLC circuit (a resistor–inductor–capacitor circuit). These filters can also be created by combining a low-pass filter with a high-pass filter. A bandpass signal is a signal containing a band of frequencies not adjacent to zero frequency, such as a signal that comes out of a ... WebA high pass filter is designed to remove unwanted low frequencies from a complex input signal. An ideal high pass filter would pass only frequencies higher than a cut-off frequency. The process of removing unwanted frequencies is called attenuation. A high pass filter primarily attenuates low frequencies so that the resulting output is ...
