chebyshev pi lc low pass filter calculator

1) a chebyshev filter is a filter whose frequency response amplitude fluctuates in the passband or stopband (flat passband, stopband ripple, or flat stopband, passband ripple). the amplitude characteristics lie within the passband. inside are equal amounts of ripples.

2) the chebyshev filter attenuates faster than the butterworth filter in the transition band, but the amplitude-frequency characteristics of the frequency response are not as flat as the latter.

3) the error between the frequency response curve of the chebyshev filter and the ideal filter is very small, but there are amplitude fluctuations in the passband.

4) a filter with ripple fluctuations in the frequency response amplitude in the passband (or "passband") is called an "i-type chebyshev filter", while a filter with a ripple fluctuation in the stopband (or "stopband") the frequency response amplitude is called a "type i chebyshev filter". ) a filter with equal ripple fluctuations is called a "type ii chebyshev filter"
