Niu Yan-wei · Modern Electronics Technique · 2007
The active filter with resistance,capacitance and Operational Amplifier(OA) is widely applied to the modern electronic technology with prominent effects.A low pass filter which approximates to Chebyshev is designed on the basis of analysis of transfer function of VCVS circuit of wave.The nominal value of capacitance is selected according to the performance parameter of the filter and its cut off frequency,and the corresponding capacitance value and resistance value are extracted through table lookup.And then,the design value after computation is obtained to define circuit parameter,and this paper comes to some valuable conclusions through the theoretical analysis and verification of the designed low pass filter with Multisim 7 software.
