High and low pass filters are simply connected in series. The output voltage \(V_{out}\) is tapped behind both filters. This variant is also called RC bandpass. If a low frequency is applied to the input, part of the voltage across the high pass filter will drop. If a high frequency is applied, the voltage drops above the low-pass filter. Bandwidth of lowpass filter? - Signal Processing Stack ... 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. Quasi-Elliptic Microstrip Low-Pass Filters Using an ...

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 … Low-pass filter - Wikipedia
