Title: FREQUENCY-MODULATED TRANSMITTING CIRCUIT AND FREQUENCY-MODULATED TRANSMITTING METHOD
Abstract:
Disclosed are a frequency-modulated transmitting circuit and a frequency-modulated transmitting method. The circuit comprises: a frequency-modulated transmitting antenna used for transmitting a frequency-modulated signal; a signal amplification circuit electrically connected to the frequency-modulated transmitting antenna; a frequency-modulated transmitting chip electrically connected to the signal amplification circuit; a transmitting microprocessor electrically connected to the frequency-modulated transmitting chip; a transmitted frequency coding switch used for adjusting a transmitted frequency point and electrically connected to the transmitting microprocessor; an audio signal socket configured for plug-in connection of an audio interface and electrically connected to the frequency-modulated transmitting chip; and an audio Bluetooth socket configured for plug-in connection of a Bluetooth module and electrically connected to the frequency-modulated transmitting chip. The present invention has the following beneficial effects: by configuring different frequency points for frequency-modulated transmission of audio signals, not only anti-interference capability of a remote control technology is improved, but also communication reliability of smart home is improved; and by applying the frequency-modulated transmitting circuit to the smart home, people's life experience is improved and smart home control functions are enriched.
