Since the presence of radio waves was discovered by the german scientist hertz in 1888, radio waves were used in a variety of fields. In 1906, the inventor of canada sent a sound for the first time via radio technology, and radio broadcasting started. Radio broadcasting is still widely used up to now, especially in the automotive field, and is a necessary module in automobiles.
The radio broadcast is composed of a transmitting end and a receiving end. The broadcaster at the transmitting end is responsible for generating sound waves (speaking changes the pressure and density in the air), converting the sound waves into audio electrical signals through an electroacoustic device, amplifying the audio electrical signals by an audio amplifier, and generating high-frequency constant-amplitude oscillation signals by an oscillator. The modulator makes the high-frequency constant amplitude oscillation signal modulated by the audio signal, and the modulated high-frequency oscillation signal is amplified and then sent to the transmitting antenna to be converted into radio wave for radiation. The radio broadcast receiving is realized by radio, the receiving antenna of the radio receives the electric wave in the air, the tuning circuit selects the signal of the required frequency, the high-frequency signal of the detector is reduced into the audio signal (i.e. demodulation), the audio signal obtained after demodulation is amplified to obtain enough driving power, and finally the broadcast content is reduced through electro-acoustic conversion. Due to the characteristics of easy interference and shielding of radio, radio broadcasting has the defect that signals are not good or cannot be received in special environments, so that clear sound information cannot be listened to.
The network broadcast is also called network radio station, is a product of the fusion of new media and traditional media, and is a new exploration of the development of the broadcast in the network era. Each large station started the traditional broadcast and the network broadcast synchronous live broadcast. The air radio station in the traditional sense is moved to the internet, and a user can listen to the radio station by logging in a radio station website or broadcasting an app. The network radio station does not need to occupy satellite orbit and frequency resources, and the broadcasting effect of the network radio station is influenced by the network bandwidth.
