WebMar 14, 2024 · Add a comment 0 The intuitive way is to compute the impedance ratio of the 2 parts as the current is shared and voltage Vin=I*Z for impedance of both together. The impedance is 1 2 π f C = X c ( f) = R this 1st order pole output is at half-power = -3dB =0.707 of Vin as the phase is now shifted 45 degrees or 50% of the 90 deg target. WebSince XL < XC, the phase angle for the current in the circuit is negative. If we increase the frequency above the resonant frequency, XL (= ω L) increases and XC (= 1/ω C) decreases. At 503 kHz, XL is about 9.48 kΩ, and XC is about 1.44 kΩ. The impedance of both together is about 9.37 kΩ (√ ( XL2 - XC2) ≈ 9.37 kΩ).
