滤波器设计相关理论
Continuous-time active filters are active networks (circuits) with characteristics that make
them useful in today’s system design. Their response can be predetermined once their excitation
is known, provided that their characteristic function is known or can be derived from
their circuit diagram. Thus, it is important for the filter designer to be familiar with the concepts
relevant to filter characterization.
