Zcomplex impedance

Zcomplex impedance

• Zcomplex(1) = 150 nF // 750 ohms + 270 ohms ( European harmonized, France Telecom & Telefonica)
• Zcomplex(2) = 230 nF // 1050 ohms + 320 ohms ( British Telecom plc )
• Zcomplex(3) = 115 nF // 820 ohms + 220 ohms ( Deutsche Telekom AG )
• Zcomplex(4) = 310 nF // 620 ohms + 370 ohms ( Telecom New Zealand )
• Zcomplex(5) = 47 nF // 510 ohms + 150 ohms ( Russian Telecom )
