Passive Low Pass Filter. A Low Pass Filter is a circuit that can be designed to modify, reshape or reject all unwanted high frequencies of an electrical signal and accept or pass only those signals wanted by the circuits designer Low Pass Filters Low Pass Filters. Low-pass filters allow signals from DC to a specified frequency to pass unimpeded with no attenuation while rejecting signals higher than this frequency. They are essentially the opposite of high-pass filters that allow higher frequencies to pass and those below the cutoff frequency to be rejected. Slotted Folded Substrate Integrated Waveguide Band Pass ...

Bandwidth (signal processing) - Wikipedia Bandwidth is the difference between the upper and lower frequencies in a continuous band of frequencies. It is typically measured in hertz, and depending on context, may specifically refer to passband bandwidth or baseband bandwidth.Passband bandwidth is the difference between the upper and lower cutoff frequencies of, for example, a band-pass filter, a communication channel, or a signal spectrum.
E.g., any digital low pass filter has a cut-off frequency that is fixed with respect to the sampling frequency, but it's not fixed as an absolute frequency! If you leave the filter coefficients unchanged and you change the sampling frequency, also the cut-off frequency will change.
