Abstract
In the conversion of a first delta modulated signal with a first bit rate into a second delta modulated signal with a second bit rate, a first and second digital signal derived respectively from the first and second delta modulated signals are compared together in an adding circuit (58) followed by an integration circuit (55). In this way an analog intermediary signal can be avoided and the circuit complexity is small.
