Detection of lightning

A method for lightning detection with a mobile lightning detector provided with an antenna, an amplifier front-end, an A/D converter and a digital signal processor, where the mobile lightning detector is a mobile RF device provided with an audio codec having the A/D converter and the digital signal processor having a digital audio processing unit, the method comprising:

• a preamplifier of the audio codec amplifying the detected lightning signal,
• the A/D converter of the audio codec performing an A/D conversion of the lightning signal, and
• the digital audio processing unit of the audio codec performing signal processing of the lightning detection,
• characterised in that the front end is connected in parallel with a microphone input so that a microphone input of an audio codec is shared by the lightning detection and another application.
