PERIPHERAL DEVICE FOR CONVERTING AND TRANSMITTING DIGITAL DATA VIA AN AUDIO CONNECTOR

摘要

The A peripheral device (PD) for converting and transmitting digital data via an audio connector (J) is intended to be connected with a host device (DE2). The peripheral device (PD) comprises at least one calculator (CPU) for performing a communication between the peripheral device and a host device. The peripheral device comprises: . a digital modulator allowing modulating digital data by encoding or/and decoding digital data frames; . an audio converter (ADC, DAC) for converting an audio signal into a digital signal and vice versa; . one output audio interface (S) and one input audio interface (M) being compatible with an audio jack connector (J) and with the audio converter (ADC, DAC); . an audio jack connector (J) for connecting the peripheral device into the host device. . an audio jack connector (J) for connecting the peripheral device into the host device.
