Quantization is the process of converting a continuous signal into a discrete one by assigning a finite number of levels or values to represent the signal. Quantization is essential for data ...

A new technique to reduce the effect of quantization noise in PCM speech coding is proposed. The procedure consists of using dither noise to ensure that the quantization errors can be modeled as ...

1Sampling rate and resolution The sampling rate is the number of samples taken per second from the analog signal, and the resolution is the number of bits used to represent each sample. The higher ...

MATLAB PCM System Simulator demonstrating digital signal processing fundamentals. Features sampling, quantization (uniform/μ-law), multiple encoding schemes, and signal reconstruction. Includes ...

This proof requires no assumptions regarding source distribution or number of quantization levels. If the code is orthogonal or transorthogonal, the bounds coincide with results obtained earlier by ...
