2017 Best Selling Receiver Made In china
what is Receiver? what is Receiver? The electromagnetic signal received by the antenna is sent to the receiver.The ideal receiver inhibits all unwanted noise, including other signals, and does not add any noise or interference to the required signal.Regardless of the form and format of the signal, it can be transformed to fit the desired characteristics of the signal processor detection circuit and then to the intelligent user interface. structure The receiver has two basic structures, one is superhetrodyne structure and the other is the direct transformation structure. A superheterodyne receiver, is the received radio frequency signal with a frequency of the vibration signal mixing or next after frequency conversion output frequency of a low intermediate frequency modulation signal . The frequency of the intermediate frequency signal is the fixed frequency difference between the oscillator signal and the frequency of the received signal. The demodulation of the final si...
