| 摘要 |
The invention relates to wireless transmission of digital data in which head phones, microwaves or infrared light are used during application. The invention uses transmitter bit timing with an extensive frequency parameter together with data word synchronization conducted with the assistance of start bits and filler bits in order to fulfill high requirements with regard to costs, power consumption and space requirements of the receiver. In addition, bit alternating and a combination of error-coding therewith provide a zero-frequency emission. A special phase locked loop is provided in order to condition the transmitter bit timing. |
