1. A portable communication apparatus comprising:
- a microphone for generating a first analog electric signal;
a reading device adapted to generate a second analog electric signal from an optical or a magnetic input signal;
a switching device having a first input coupled to the microphone, a second input coupled to the reading device, and a control input for receiving a control signal for selecting whether the first or the second analog electric signal is to be forwarded to a processing device;
wherein the processing device has an input coupled to an output of the switching device for receiving either the first or the second analog electric signal; and
wherein the processing device is adapted to process the first and second analog electric signals through a single signal path.

Abstract
A portable communication apparatus has a microphone and a processing device with an input operatively coupled to the microphone. The processing device generates a digital output signal from a first electric signal received from the microphone. A reading device in the portable communication apparatus generates a second electric signal from an optical or magnetic input signal. The processing device is operatively coupled to the reading device, so that the second electric signal from the reading device may be received at the input of the processing device.
