Which type of band does not use a complex modem device?
Correct answer: B. Baseband
- A. Serial
- B. Baseband
- C. Broadband
- D. Distortion
Explanation
The answer is (b) Baseband. Baseband signals are analog signals that represent information by continuously changing some property of the signal, such as voltage or amplitude. They do not require complex modulation and can be transmitted directly over a cable or other medium. Therefore, baseband is the type of band that does not typically use a modem.
