in second order filter attenuation to the frequencies in stop band is higher then first order filters.

How is the bandwidth of a band-reject filter determined

High Pass Filter - band - was created in 1996.

Electronic filters are used for distinguish the frequency spectrum of EM Wave. it can be high pass filter low pass filter or band pass filter or band stop filter.

Advantage are they are higly sensitive to frequency ranges , they amplify the signal partially.

and disadvantage is that the value or inductor and capacitor depend on the temperature so effective temperature can cause the change in frequency to passed by that filter.
