Measuring attenuation, gain, phase shift or derived characteristics of electric four pole networks, i.e. two-port networks; Measuring transient response (in line transmission systems H04B3/46)

Introduced: September 1968

Title

Titles differ between systems:

IPC: Measuring attenuation, gain, phase shift, or derived characteristics of electric four-pole networks, i.e. two-port networks; Measuring transient response

CPC: Measuring attenuation, gain, phase shift or derived characteristics of electric four pole networks, i.e. two-port networks; Measuring transient response (in line transmission systems H04B3/46)

Full Title

Full titles differ between systems:

IPC:

Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring attenuation, gain, phase shift, or derived characteristics of electric four-pole networks, i.e. two-port networks; Measuring transient response

CPC:

Arrangements for measuring resistance, reactance, impedance, or electric characteristics derived therefrom > Measuring attenuation, gain, phase shift or derived characteristics of electric four pole networks, i.e. two-port networks; Measuring transient response (in line transmission systems H04B3/46)

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.
