Abstract: This paper describes a digital speech interpolationadaptive differential PCM bit reduction technique in which digital speech interpolation (DSI) is combined with ADPCM encoding. A highly ...

Pulse code modulation (PCM) is a technique that converts analog signals into digital bits by sampling, quantizing, and encoding them. PCM is widely used in digital communication, audio, and video ...

This section introduces the fundamental concepts of analog modulation and demodulation used in communication systems. It explains how a low-frequency information signal is combined with a ...

We've previously analyzed I2S (Inter-Integrated Signaling) (I2S). In addition to I2S, PCM is also a common interface for transmitting digital audio signals. It's widely used for communication between ...

Adaptive PCM codecs leverage real-time signal analysis and machine learning algorithms to optimize encoding parameters dynamically, ensuring consistent audio quality across fluctuating network ...
