The sensitivity analysis of even order biquadratic elliptic filters
M. PASKO and T. ADRIKOWSKI
In this paper, the sensitivity analysis of the elliptic filters realized by using biquadratic structures was carried out. The influence
of spread the structure parameter values on the shape of the frequency characteristic of the filter transmittance modulus was analyzed. The analysis was limited to the case of even order low-pass filter. Defining the proper class of the sensitivity coefficients, the changes influence of individual structure parameters on the deviation of basic parameter values of the characteristic was considered. The considerations were illustrated by the numerical example.
 
Keywords:
elliptic filter, biquadratic structures, frequency filter characteristic, sensitivity analysis, sensitivity coefficients
