Abstract (en)

[origin: WO9957808A1] A control device can automatically tune an external or auxiliary input signal to the frequency currently being received by a target receiver. Therefore the control device uses noise from a target receiver to tune the auxilary signal to the frequency being receied by the target receiver. The noise is mixed with a modulated signal bearing the auxiliary signal in order to provide an output signal which contains a component at the target reception frequency.
