The audio data on the CD is in the form of PCM, or pulse code modulation. In PCM, the amplitude of the analog audio waveform is sampled periodically, and the samples are quantized: Each sample is ...

In practical signal processing, it is necessary to quantize the sampled signals. Quantization is considered a necessary step to digitalize signals and realize the high-efficient transmission of ...

It's common to use high-precision floating-point operations on theoretical study of the Low Density Parity Check (LDPC) codes, but it is difficult to implement it in practical application. Therefore, ...

The various methods for converting analogue signals into the form of pulse-code modulation and back again are reviewed. Reasons are given for preferring a particular method of conversion called ...
