This JRP aims to improve impedance metrology at the lowest uncertainties by making the transition from measurements performed at predefined values and relative phase angles for selected frequencies to any ratio over the complete audio frequency range (20 Hz to 20 kHz). This will be achieved with two different types of impedance bridges: Josephson bridges and digital bridges.
