The correct Answer is:
To analyze the statements given in the question, we will break down each statement and evaluate their truthfulness step by step. ### Step 1: Understanding Statement 1 **Statement 1:** "The transmission using FM is more efficient as compared to AM." - **Explanation:** Frequency Modulation (FM) is generally considered more efficient than Amplitude Modulation (AM) for several reasons: - FM signals are less susceptible to noise and interference compared to AM signals. This is because noise affects amplitude, and since FM relies on frequency changes, the impact of noise is minimized. - FM allows for better sound quality and fidelity, making it suitable for music and high-quality audio broadcasting. ### Step 2: Understanding Statement 2 **Statement 2:** "In FM, amplitude and therefore power handled is constant." - **Explanation:** In FM, the amplitude of the carrier wave remains constant while the frequency varies according to the modulating signal. This means: - The power of the FM signal is also constant because power is proportional to the square of the amplitude. Since the amplitude does not change, the power remains constant. - In contrast, in AM, the amplitude of the carrier wave varies, which leads to fluctuations in power. ### Step 3: Evaluating the Truth of Each Statement - **Truth of Statement 1:** True. FM is indeed more efficient than AM due to its resilience to noise and better sound quality. - **Truth of Statement 2:** True. In FM, the amplitude is constant, which means that the power handled is also constant. ### Step 4: Conclusion - Since both statements are true and Statement 2 correctly explains why Statement 1 is true, we can conclude that both statements are valid. ### Final Answer: Both statements are true, and Statement 2 provides a correct explanation for Statement 1. ---
