Determination of degrees of Butterworth-, Tschebyscheff-, and Cauer Filters

Input of attenuation in pass- and stopband, and frequency at which the stopband starts, respectively:


Butterworth Filter

alpha_p=dB (maximal attenuation in passband)
alpha_s=dB (minimal attenuation in stopband)
omega_s= (start of stopband)
Determination of filterdegree:

Tschebyscheff Filter

alpha_p=dB (maximal attenuation in passband)
alpha_s=dB (minimal attenuation in stopband)
omega_s= (start of stopband)
Determination of filterdegree:

Cauer Filter

alpha_p=dB (maximal attenuation in passband)
alpha_s=dB (minimal attenuation in stopband)
omega_s= (start of stopband)
Determination of filterdegree:
