Question
Which statement is FALSE for PLL used for demodulation
of FM?Solution
In a Phase-Locked Loop (PLL) used for FM demodulation, the loop operates as a negative feedback system. Its main advantage is that it reduces noise power at the demodulator output, which makes PLL-based FM demodulation superior to simple slope detection. However, PLL does not increase the bandwidth; instead, the loop bandwidth is controlled and usually limited to track the FM signal while rejecting unnecessary noise. So, the false statement is: “PLL uses feedback system thus increase the bandwidth.”
