Question

Please make it clear handwriting. I will leave positive feedback

For a series RLC bandreject filter with center frequency 2.4 kHz, quality factor 3, and with a 200 nF capacitor, R SL V/8) V.

R= L = Wc1 = Wc2 b. (15) Calculate the amplitude frequency response and plot it using linear scales.

C. (20) Assume now that an external load, R, is connected to the output of the network at terminal V. (S). Assume that Rį = R

Answer #1

fo or 2.4 10 = ZIVLC 2TVL 200 10-9

→L= 1 4 * T *7 * 2.4 * 2.4 * 106 * 200 * 10-9 21.9881mH (Approx)

Quality Factor Q 2*1* fe* 1 R R 2 * T * fe* 0

→ R= 2* 7 * 2.4 * 1000 * 21.9881 * 10-3 3 110.5242454812

1 wel R 21 + R2 412 + LC

Wci = 110.52424548 2 * 21.9881 * 10-3 + 110.524245482 4*21.9881210-6 + 1 21.9881 * 10-3* 200* 10-9

c1 2513.274+v6316546.81644 + 227395727.689 = 12774.377 rad/sec

Wc2 R 2 + R2 4L2 + 1 = 2513.274+1223712274.5 = 17,800.925 rad/sec LC

No resonance will take place on non zero frequency if we connect a resistor of the same value across capacitor...
