Of the following which is the preferred modulation scheme for digital ...
Pulse Code Modulation (PCM) is the preferred modulation scheme for digital communication. PCM is a method that is used to digitally represent analog signals by sampling and quantizing them. It is widely used in various applications such as telecommunication, audio recording, and data transmission.
PCM works by taking samples of the analog signal at regular intervals and converting each sample into a binary code. These binary codes represent the amplitude of the analog signal at that particular instant. The binary codes are then transmitted over a digital communication channel.
There are several reasons why PCM is the preferred modulation scheme for digital communication:
1. Higher Accuracy: PCM offers higher accuracy compared to other modulation schemes. By sampling the analog signal at regular intervals, PCM captures the exact amplitude of the signal at that instant. This ensures that the received signal is a faithful reproduction of the original analog signal.
2. Noise Immunity: PCM is highly immune to noise and interference. Since the analog signal is converted into a binary code, any noise or interference introduced during transmission can be easily detected and corrected using error detection and correction techniques.
3. Efficient Bandwidth Usage: PCM efficiently utilizes the available bandwidth. The analog signal is sampled at a rate higher than the Nyquist rate, which ensures that the original signal can be accurately reconstructed from the samples. This allows for efficient utilization of the available bandwidth.
4. Compatibility with Digital Systems: PCM is compatible with digital systems, making it easy to integrate with existing digital communication infrastructure. It can be easily processed, stored, and transmitted using digital devices and systems.
5. Flexibility: PCM offers flexibility in terms of signal processing and manipulation. The binary codes can be easily manipulated and processed using digital signal processing techniques, allowing for various operations such as filtering, compression, and encryption.
In conclusion, Pulse Code Modulation (PCM) is the preferred modulation scheme for digital communication due to its higher accuracy, noise immunity, efficient bandwidth usage, compatibility with digital systems, and flexibility in signal processing.
