Band-pass Filters
A "band-pass" electronic filter is a tuned electronic circuit, which allows electrical signals operating at a certain frequency to pass from one region of the circuit to another. If the frequency of an electrical signal is greater than or less than the frequency the band-pass filter is set for, the filter creates electrical impedance (akin to electrical resistance in a DC circuit) that prevents any electrical power from that signal from passing through the band-pass filter. However, if the signal frequency is at or near the set frequency of the band-pass filter, the filter will allow the signal through.
Band-stop Filters
A "band-stop" electronic filter is a tuned electronic circuit that acts in a manner opposite to the band-pass filter. If the frequency of an electrical signal is greater than or less than the band-stop filter is set for, the signal will pass through the filter. As the signal frequency becomes closer to the band-stop filter's set frequency, the filter creates electrical impedance that prevents any electrical power from that signal from passing through the band-stop filter.
