It mainly consists of dot-lattice constructor,
quantizer, and decoder.
Real valued parts are quantized based on scalar
quantizer as follows:
Wagdy [10] gives exact fuctional relation between Probability Density Funciton (PDF) and variance of the quantization error if the sinusoidal signal is applied to the uniform
quantizer:
This paper proposes the non-uniform three-level scalar
quantizer designed for Gaussian probability density function (pdf), followed by the variable length coding (VLC).
Ignore the impact of the
quantizer; the sequence [[z.sub.k]] directly comes into the digital filter; by smoothing, the digital filter outputs a more reliable correcting sequence {[y.sub.k]} to digital clock: [y.sub.k] = D(z)[z.sub.k].
Quantization also has become a research hotspot these years, paper [17] notes that quantization process plays an important role in the networked control systems, an adaptive
quantizer can help to alleviate network congestion and maintain system stability, paper [18] proposes a quantized state feedback strategy for global and asymptotical stabilization of the networked control systems, papers [19, 20] address the problem of output feedback control for networked control systems with limited information, it should be noted that the impact of quantification cannot be ignored, and, in [18, 19, 21], the quantization deviation is disposed as an uncertainty.

Alongside the current lineup of Canon 4K HDR reference display, the Canon DP-V2411 supports Electro-Optical Transfer Functions (EOTF) such as Hybrid Log-Gamma, a broadcasting HDR standard; Perceptual
Quantizer (PQ), a HDR standard for film production and transfer; and Canons proprietary log gammasCanon Log, Canon Log 2 and Canon Log 3.
Sampler and
quantizer blocks are embedded on the throttle ECU I/Os to virtually emulate different sampling and quantization levels.
An efficient
quantizer can reduce the amount of bits; for example, Wang et al.
After DCT, a
quantizer with quantization table is used to provide higher compassion ratio in transmission by approximating a continuous set of values in image data to a finite (preferably small) set of values.
