Baseband modulation: It is a kind of demodulator. In the field of communication and network, the meaning of bandwidth is different from the above definition. It refers to the difference between the highest frequency and the lowest frequency that can be used by network signals, or the width of the frequency band. , which is the so-called channel bandwidth, which is also the most rigorous technical definition.
Radio Frequency Modulation: Modulator is the abbreviation of adjacent frequency modulator, also often called radio frequency modulator or TV modulator, which is one of the main equipment in the cable TV front-end computer room.
The difference between the two:
1. Different functions: baseband modulation refers to network broadband and radio frequency modulation TV modulators.
2. The modulation objects are different: the baseband modulation is for the network, and the radio frequency modulation is for the TV.
