Simple Bandpass Amplifiers
In addition to the RLC tuned circuits of Chapter 8, highly selective bandpass circuits can be achieved with lowpass amplifiers together with resistorcapacitor combinations in overall negative or positive feedback configurations. These active RC configurations are a most interesting study in themselves. In this section, only two basic types are introduced to illustrate the realization techniques.
