1. There is no baseband audio or video input to the translator. 2. Digital baseband signals are carried over fiber, using CPRI standard. 3. The frequencies subtract, producing the baseband signal for that channel again. 4. Demodulation takes place at baseband using low-pass filters and amplifiers. 5. MultiLevel optical recording is an example of baseband pulse-amplitude modulation. 6. The second switching stage mixes the intermediate frequency to baseband . 7. A baseband processor typically uses its own RAM and firmware. 8. In an OFDM system, the baseband signal consists of several subcarriers. 9. This composite baseband signal is typically used to modulate a main RF carrier. 10. In many commercial data radio applications, audio baseband modulation is not used.
