Active Filter Circuits and Phase-Locked Loop (PLL), the applicability in instrumentation, low pass, high pass and band pass filters are explained. The frequency selection in audio or music systems is utmost important. The selection of lower and higher cut-off frequencies decides the quality of the filters. And in public address or audio or stereopho

,,,he work of inductor. The real inductors cannot be fabricated in the ICs, but this could be possible with gyrators. Gyrator is a simulated circuit of inductor. Large value inductors and extensive adjustable inductance range are easily implemented using resistors, capacitors and operational amplifiers
