) willhave a peak amplitude at a center or resonant frequency f0 = 800kHz., with a bandwidth (i.e.difference between the upper and lower 3dB frequencies) of 10kHz. The circuit could be used to“tune” to an AM radio station with an 800 kHz. carrier frequency and provide the 10kHz. bandtypically used for audio reception. The quality factor for the circuit (Q) is the ratio of f0 to thebandwidth, giving us Q = 80 for this circuit.A slide range of 750,000 to 850,000 is selected.The callback function applies standard AC circuit analysis, using phasors and compleximpedances, to find the steady state sinusoidal voltages across R, L and C. These three voltages,VR, VL and VCrespectively, along with the source voltage Vin are plotted over one periodT = 1
