The correct Answer is:
To solve the question regarding the process of superimposing signal frequency (i.e., audio wave) on a carrier wave, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Terms**: - **Carrier Wave**: This is a waveform (usually a sine wave) that is modulated with an information signal for the purpose of conveying information. - **Signal Frequency**: This refers to the frequency of the information signal, such as audio waves, that we want to transmit. 2. **Identifying the Process**: - The question asks for the process of superimposing the signal frequency onto the carrier wave. This means we need to find a term that describes this action. 3. **Analyzing the Options**: - **Transmission**: This refers to the act of sending waves from one place to another. It does not specifically refer to the superimposition of signals. - **Reception**: This is the process of receiving signals, typically converting electromagnetic waves into electrical signals. It does not involve superimposing. - **Detection**: This refers to identifying or detecting the presence of a signal. Again, it does not involve superimposing. - **Modulation**: This is the process of varying a carrier wave in order to use that wave to convey information. This includes superimposing the signal frequency on the carrier wave. 4. **Conclusion**: - The correct answer is **Modulation** because it specifically refers to the process of superimposing the signal frequency (audio wave) onto the carrier wave. ### Final Answer: The process of superimposing signal frequency (i.e., audio wave) on the carrier wave is known as **Modulation**. ---
