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 ...

Simulating a Differential Pulse-Code Modulation (DPCM) with Uniform Quantizer DPCM: In Differential Pulse Code Modulation the quantized signal sent to the receiver is the difference between the ...

DPCM (Differential Pulse Code Modulation) can be considered as a generalization of Delta coding where the signal quantized and sent to the receiver is the difference between the current sample (time n ...

Delta modulation is a technique of encoding analog signals into digital bits by comparing the difference between successive samples. PCM, or pulse code modulation, is another technique that ...

Differential pulse code modulation (DPCM) and predictive quantizing are two names for a technique used to encode analog signals into digital pulses suitable for transmission over binary channels. It ...

The objectives of this investigation were twofold: 1) to demonstrate the utility of the nine-point speech "goodness" rating scale as a method for scaling user opinion of speech quality, and 2) to use ...
