Question

Please Help. This is a PSPICE Simulation pro​​​​​​blem. Thanks.
Equipment For the laboratory experimentation, the standard laboratory equipment (function generator, oscilloscope, multimeter) will be used along with a capacitor (0.027 μF), an inductor (10 mH for the series RLC circuit and 1 mH for the parallel RLC circuit), and a resistor (to be determined in your prelab work)

Answer 1

Given w = 2 pi times 10^4 c = 0.027 mu F using voltage division rule v_0 = 1/sc + v_i/R + 1/sc rightarrow v_/v_i = 1/sc/SCR + 1/SC Therefore v_0/v_1 = 1/1 + SCR = 1/RC/s + 1/RC To have corner frequency at f = 10 k Hz 1/RC = 2 pi times 10 times 10^3 Therefore R = 1/2 pi times 10 times 10^3 times 0.027 times 10^-6 = 589.46 Ohms The transfer function has a pole at 1/RC Therefore this a low pass filter with cut off frequency at 1000 k R_a = 21 Ohm L = 10 m H v_0 = R_a + SL/R + R_a + SL \r\n v_0/v_i = 21 + 0.015/21 + r + 0.018 = 0.01 [s + 2100]/0.01 [s + 21 + R/0.01] Therefore v_0/v_i = s + 2100/s + 21 + R/0.01 To have corner frequency at 1000 Hz 21 + R/0.01 = 10000 times 2 pi Therefore 2100 + 100 R = 2 pi k times 1000
