Abstract:
1. An RF transmitting apparatus for converting audio signals output from a sound card of a computer to RF signals and transmitting the RF signals, the RF transmitting apparatus comprising: an interface coupled to the sound card for receiving the audio signals from the computer, and rearranging the audio signals to form data packages; a reference clock module for sending reference clock signals; a modulating module coupled to the interface and the reference clock module for receiving the data packages, the modulating module is capable of adjusting a frequency of a carrier wave with a constant frequency of the reference clock signals, and modulating the carrier wave with the data packages to generate modulated signals; an amplifying module coupled to the modulating module for amplifying the modulated signals; a transmitting module coupled to the amplifying module for converting the modulated signals to the RF signals; and an antenna coupled to the transmitting module for transmitting the RF signals.
