Interface Circuit

The interface circuit is housed inside steering gearbox near pinion. It rectifies and amplifies signals from torque sensor and rotation sensor and transmits steering signals to control unit. A phase compensating circuit is also built in, which changes output signals in accordance with drive signals input from control unit. See Fig 1 .
