1. Noise Immunity: Pulse-code modulation is less affected by noise and distortion which makes it more reliable. 2. Low Bandwidth Requirements: Pulse-code modulation requires lesser bandwidth as compared to other modulation methods. 3. High Quality: Since pulse-code modulation can inherently reduce the amount of noise and distortion, it can produce high-quality recordings. Therefore, PCM is used for digitally encoding music. 4. Efficiency: Since PCM formatting compresses the data without losing any of its resolution, it is more efficient than other formats. 5. Compatibility: PCM is compatible with most devices which means you will be able to play it virtually anywhere.
