EXPERIMENT 6BAND-PASS FILTERS1. AIM OF THE EXPERIMENTTo obtain frequency characteristic of the bandpassfilter.2. INTRODUCTIONA band-pass filter circuits allows signals of frequencies in specific range and attenuates theout of the range. A series RLC circuit is a band pass filter. A passive band-pass filter has threecharacteristic frequency which are named as center ( f.), low cut-off ( f;) and high cut-off ( f) frequency. The bandwidth (BW) of the filter is defined as difference f, and f.L.Figure 1: The RL High-Pass FilterThe circuit parameter for series RLC circuit are defined as:X=1/@Cand total reactance and impedance of the RLC circuit is obtained as:X, = X, -XcZ = R+ jX,The center, low and high cut-off frequencies of the filter with related the circuit parametersare calculated as:1fo27 LCR.4 L 2n2LLC 3. PRELIMINARY WORK1. Calculate the cut off frequencies and central frequency of the circuit given in Figure 1with C=10 uF, R= 20 2 and L=1 mH.2. Plot the gain (VotV;) of the circuit versus frequency.3. Calculate bandwidth of the filter.Please note that signal source has 50 ohm impedance, so that you have to take totalresistance of the circuit as 50+20=70 ohm value for calculation, not only 20 ohm.

We need to find out lower and upper cut off frequency and bandwidth in rlc circuit.
