Ling Zhi electronic stereo dual voice wireless simultaneous interpreting
——Dual signal frequency modulation（FM）Transmitting and receiving module
share2It consists of two modules，1Transmitting modules，1Multiple receiving modules。
The transmitting module uses a low power consumption、Fully functional stereo FM transmitter single chip，Suitable for stereo、Modulation and wireless transmission of dual voice or dual analog signals，Suitable for portable audio player、auto parts、Mobile phone andGPSPersonal navigation equipment。Transmission frequency range from76MHz to108Megahertz，Step size50Kilohertz，FM band support worldwide，Also supportRDS/RBDSdata transmission。
The receiving module also uses a low power consumption、Fully functional stereo FM receiver single chip，Suitable for stereo、Wireless reception and demodulation of dual voice or dual analog signals，For mobile phones、MP3Systems such as players and portable radios。It also supportsRDS/RBDSData receiving。A low-pass filter is designed at the back end of the module，It is helpful to improve the quality of signal demodulation。
The wireless transmitting and receiving module can be used as a common wireless communication module in the National College Students' electronic design competition，For example, dual channel voice simultaneous interpreting wireless transceiver system.（2019YearGtopic）、Simplex wireless call system（2005YearDtopic）Wireless transceiver module in system；It can also be used by radio enthusiasts。
The main performance indexes of the module are as follows：
The interfaces of transmitting module and receiving module are shown in the figure。

The modulation signal is modulated using the transmitting module，It is demodulated using the receiving demodulation module。The distance between transmitter and receiver is about4.5mand6.5mThe partial waveform demodulated from the overall test is shown below，The closer the receiving and transmitting distance is, the better the receiving effect is。
Two modulation frequencies240Hzand350Hz-Launch distance approx4.5m
Two modulation frequencies250Hzand340Hz-Launch distance approx6.5m
Both modulation frequencies are1kHz-Launch distance approx6.5m
Both modulation frequencies are3kHz-Launch distance approx6.5m
Both modulation frequencies are5kHz-Launch distance approx6.5m
Both modulation frequencies are6kHz-Launch distance approx6.5m
Both modulation frequencies are8kHz-Launch distance approx6.5m
Both modulation frequencies are9kHz-Launch distance approx6.5m
