FILTER CIRCUIT FILTER               Filter is an electronic circuit. Filter circuit is very useful electronic device which can filter pulse of frequency. Filter circuit can stop or pass particular band of frequency. TYPES OF FILTER CIRCUIT               1)Low pass filter circuit.               2)High pass filter circuit.               3)Band pass filter circuit.               4)Band stop filter circuit. 1)LOW PASS FILTER CIRCUIT Low pass filter circuit                                                       This filter circuit allow only low frequency and which reject above the all cut-off frequencies its called low pass filter. NAME OF THE COMPONENTS WHICH MADE THIS CIRCUIT               This circuit made of two components----1)Inductor , 2)Capacitor. Series connected----Inductor. Parallel connected----Capacitor. USED OF LOW PASS FILTER CIRCUIT               1)Low pass filter used in rectifier circuit. OTHER NAME OF LOW PASS FILTER CIRCUIT               1)Integrating network.          

PARALLEL RESONANCE CIRCUIT  Parallel resonance circuit Inductor, Capacitor, and Resistor connected are parallel line its called parallel resonance circuit. RESONANCE FREQUENCY OF PARALLEL RESONANCE CIRCUIT F r =1/2 ∏ √L.C   POWER FACTOR  Power factor is unity of parallel resonance circuit.

CAPACITOR               It is a passive components. Capacitor have storing ability. Which can store electric energy in the form of electric charge. Has the ability to store charge which neither a resistor nor an inductor can do. CAPACITANCE               The charge storage ability of a capacitor is called the capacitance of a capacitor. UNIT OF CAPACITANCE               The unit used to measure capacitance is Farad (F), its symbol (C). FARAD               If a voltage of one volt causes one coulomb of charge to deposited in a capacitor , its capacity will be one farad.              1 FARAD=1 Coulomb / 1 volt                                                                           =   9 × 10 11 e.s.u                              e.s.u= Electrostatic unit                                   1 µ F=10 -6 F                                           1nF=10 -9 F                                         1pF=10 -12 F              Q=C.V           Q=Charge,coulomb             C=Capacity , farad
