Skalaarikvantointi
Skalaarikvantointi, also known as scalar quantization, is a fundamental technique in digital signal processing and data compression. It involves mapping a continuous or large set of discrete input values to a smaller, finite set of output values. This process effectively reduces the number of bits required to represent the original data, leading to compression.
The core idea of scalar quantization is to divide the range of possible input values into several
The performance of a scalar quantizer is typically measured by its rate (the number of bits per
Scalar quantization is a building block for more complex compression schemes, such as those used in audio
