Band-Pass filters
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
The primary function of a filter is to reduce the level of, or ideally eliminate, unwanted frequencies. There are three basic types of filter:Low pass which permits frequencies below a predetermined frequencyHigh pass the opposite of low passBand pass which permits a predetermined range of frequenciesNotch which permits everything except a predetermined range of frequenciesFilters can be analogue using resistor-capacitor or indutctor-capacitor networksor digital
The roll off filter removes low frequencies. Usually at about 75 HZ and bellow.
It must be an analog filter. The high frequencies must be attenuated before any digital sampling takes place, to ensure that these high frequencies are not sampled as false signals. See the related link.
Only frequencies in the pass band range will be allowed through the circuit. Other frequencies will be attenuated based on the RC values picked.

Filter is an electronic device which passes specific frequency and attenuates all other.There are 4 types of filters: 1) Highpass - passes only high frequencies 2)Lowpass - passes only low frequencies 3)bandpass-passes only specefic band of frequencies 4)band reject-passes all frequencies excepting desired band
A band-pass filter blocks or attenuates frequencies outside of a certain range, while it accepts frequencies from within that range. The range of frequencies it will accept is determined by its Q-factor. A filter with a high Q-factor will have a narrow range of accepted frequencies, whereas a filter with a low Q-factor will have a wide range of accepted frequencies.
when imperfect receiver filter allow nearby frequencies to leak into the passband the interference produced is call adjacent channel interference Engr Aamir Naeem facebook id: Aamirnaeem77@gmail.com

Yes, if the passband of the first filter includes that of the second one, and the light contains wavelengths that fall within their common passband.

Advantage is that it has the most flat passband meaning that it is very good at simulating the passband of an ideal filter. The disadvantage is that it has a horrible stopband because it gradually goes to zero so some parts of the stopband are still passed. However, for an nth-order Butterworth Filter, as n increases, the closer it is to an ideal filter. However, it is highly impractical to build a ridiculously high order Butterworth filter.
A low pass filter allows "low" frequencies to pass through a circuit and blocks higher frequencies.
It minimizes the error between the idealized and the actual filter characteristics over the range of filter, but with the ripples in the passband.Note:Butterworth filter does not give the sufficiently good approximation across the complete passband in many cases. And the Taylor's series is often not suited to the way specifications are given to the filter.For the IIR filter, the Chebyshev error is minimized over the passband and a Taylor's series approximation atis used to determine the stopband performance. This mixture of methods in the IIR case is called the Chebyshev filter

Advantages of elliptic filters include having steeper roll-off rates and a more compact design compared to other filter types. Disadvantages can include higher sensitivity to component variations, leading to potential tuning and manufacturing challenges.
