Question

For the following circuit, answer questions 15 through 17. Show all work. R2 1k0 RI SKO Rin Vout 1k0 C2 HE C1 HH 1F Vin F RL Siko 1Vpk 1kHz 0 R1 Siko 15) Identify Circuit 16) What is the cutoff frequency Fc of the circuit. 17) What is the gain in decibels of the circuit at a frequency F = 1.2 KHz.

Answer 1

given Circuit R2 lkn RE Rin Iki lkn Vout + (2 RL Ikr It (ЦЕ luf RI lkn Vin 15) The above circuit is a Second order high pass filter using op amp. 16) (utt off frequency fc of the Circuit?- are different if Resistor and capacitors Values - fi an RR 2C, C2 same are if Resistor and capacitors Capacitors Valves fc = QARC

So we have same Same Capacitor and Resistor values. = 1 UF 9 =12 Ri= R2 = lkn Cutt off frequency fc = QT RC 103 - = anx 1x10x Ixio 6.28 0.1592 x103 fia 159.2 HZ. 17) gain in decibels PRA =Rf Av= HRA RB RB = Rin 5x103 Ave It 1x 103 Av=6 (Av) de = 20 log (6) 11 (Av) dB 15.56 dB
