A method for frequency transposition in a communication device Or a hearing device, respectively, is disclosed by transforming an acoustical signal into an electrical signal (s) and by transforming the electrical signal from time domain into frequency domain to obtain a spectrum (S). A frequency transposition is being applied to the spectrum (S) in order to obtain a transposed spectrum (S'), whereby the frequency transposition is being defined by a nonlinear frequency transposition function. Thereby, it is possible to transpose lower frequencies almost linearly, while higher frequencies are transposed more strongly. As a result thereof, harmonic relationships are not distorted in the lower frequency range, and at the same time, higher frequencies can be moved to a lower frequency range, namely to an audible frequency range of the hearing impaired person. The transposition scheme can be applied to the complete signal spectrum without the need for switching between non-transposition and transposition processing for different parts of the signal. Therefore, no artifacts due to switching are encountered. A higher transmission quality is obtained because more information is taken into account for the transmission.

The invention concerns a power diverting circuit for creating a supply voltage for a signal processing circuit from a source of data signals each having a high or a low potential respectively corresponding to a first or a second logic state. The circuit comprises a first terminal for receiving the data signals, a second terminal for providing the supply voltage, a switch coupled between the first terminal and the second terminal for selectively connecting and disconnecting the first terminal and the second terminal, and an inverter for inverting the state of the data signals. The inverter, which has an input terminal connected to the first terminal and an output terminal for providing the inverted data signals to the signal processing circuit, is responsive to the state of the data signals received at the first terminal to control the operation of said switch means.
