Modulation is a process of superposing
- A low frequency radio signal on low frequency audio waves.
- B high frequency audio signal on low frequency radio waves.
- C low frequency audio signal on high frequency radio waves.
- D high frequency radio signal on low frequency audio signal.
Answer & Solution
Correct Answer
(C) low frequency audio signal on high frequency radio waves.
Step-by-step Solution
Detailed explanation
Low frequency audio signal cannot be transmitted as such over long distances. Therefore. to overcome this difficulty, the low frequency audio signal is superposed on a high frequency wave (carrier wave). This process is called modulation.
