The working principle of the radio is as follows: the transmission part: the phase-locked loop and voltage controlled oscillator (VCO) generate the transmitted RF carrier signal, which is buffered and amplified, and the power amplifier generates the rated RF power, and passes the antenna switch and low-pass filter to suppress the harmonic component, and then is transmitted through the antenna. Receiving part: The receiving part is generally a two-frequency superheterodyne mode.
Walkie-talkie is a wireless communication device, its working principle is mainly based on the transmission and reception of radio waves. The transmitting part of the walkie-talkie is mainly composed of a microphone, a modulator, a power amplifier, etc. When the user presses the transmit button, the sound received by the microphone is converted into an electrical signal, which is processed by the modulator and loaded onto the high-frequency current.
Principle of digital walkie-talkies: The basic principle of digital walkie-talkies is to convert analog speech into digital signals, and then modulate to the radio frequency. Since the transmission is a digital signal, of course, the device can also transmit data directlyPlease. The emergence of digital walkie-talkies is also to save radio spectrum, so digital walkie-talkies are mostly a voice channel equivalent to occupy 25kHzk bandwidth, that is, half the frequency than ordinary analog walkie-talkies.
