A PCM-Based Vocoder/Decoder, a voice codec software based on PCM of voice signals to send over data network, whose quantizer provides both mid-rise and mid-tread quantization techniques, and an ...

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 ...

Pulse Code Modulation (PCM) is the simplest form of waveform coding. Waveform coding is used to encode analogue signals (for example speech) into a digital signal. The digital signal is subsequently ...

Abstract: An adaptive differential pulse-code-modulation technique for encoding and decoding has been implemented using the Bell Laboratories digital signal processor integrated circuit. The ...

Raytheon Co., Tucson, Ariz., is being awarded an $8,761,875 modification to a previously awarded firm-fixed-price contract for the replacement of the Pulse Code Modulation (PCM) Encoder due to ...
