There are two basic types of radio receivers: coherent and noncoherent. The difference between the two terms is: Select your answer. In a synchronous receiver, the frequencies utilized for demodulation are either not created in the receiver or are fully independent of the transmitter's carrier frequency. The frequencies generated in the receiver and used for demodulation are synchronized to oscillator frequencies generated in the transmitter in an asynchronous receiver. In a synchronous receiver, the receiver's demodulation frequencies are synchronized with the transmitter's oscillator frequencies. In an asynchronous receiver, the frequencies utilized for demodulation are either not created or are completely dependent on the transmitter's carrier frequency.
