For the circuit given below, the value of z11 parameter is ____________(a) z11 = 4 + j6 Ω(b) z11 = j6 Ω(c) z11 = -j6 Ω(d) z11 =-j6 + 4 ΩI had been asked this question in my homework.This is a very interesting question from Advanced Problems on Two Port Network in division Two-Port Networks of Network Theory |
Answer» CORRECT choice is (a) z11 = 4 + j6 Ω To explain I would say: Z12 = j6 = z21 z11 – z12 = 4 Or, z11 = z12 + 4 = 4 + j6 Ω And z22 – z12 = -J10 Or, z22 = z12 + -j10 = -j4 Ω ∴ [Z] = [4+j6:j6; j6:-j4] Ω. |
