A multibit approach is applied at quantizer level to reduce the noise spikes and the results show the rms noise power for 2 bit controller is 3.
This contract provides for development of a quantizer that realizes the full potential of a low-jitter photonic sample and holds (pS&H) in a direct conversion digital receiver based on a photonics-enabled, analog-to-digital converter (pADC) with a 4GHz IBW and greater than 10 effective number of bits (ENOB) for an undersampled 12 GHz signal.
Support of high dynamic range (HDR)- Allows for enhanced contrast by signaling the electro-optical transfer function (EOTF) as SMPTE ST 2084 Perceptual Quantizer (PQ).
He has received an NSF grant titled “Data-Driven Adaptive Quantization for Distributed Inference,” addresses a fundamental challenge of quantization for distributed inference in a sensor network environment, where the optimum quantizer generally cannot be implemented due to its dependence on unknown parameters associated with the random events being monitored by the sensor network.
Moreover, it closes (at least for images and any other data that can be represented as a Riemannian manifold) the open problem (related to Zador's Theorem) of finding a constructive method to determine the dimension of a quantizer (Zador's proof is nonconstructive).
Striving for higher precisions in measurement technology naturally leads to methods, which can shift the resolution limit of the quantizer usually represented by the analog-to-digital converter (ADC) under the lowest significant bit (LSB).
2002), a two-dimensional vector quantizer with a fixed-size codebook was considered.
A Quantizer simply reduces the number of bits needed to store the transformed coefficients by reducing the precision of those values.

The assumptions that the SPIHT quantizer makes about the relationship between subbands hold well for scalar wavelet, but they do not hold for multiwavelets for the multiwavelet transform destroys the parent-children relationship that SPIHT presumes as illustrated in Fig.
Each IFM receiver also incorporates a digital amplitude quantizer that characterizes the RF amplitude and generates a standard video signal for measuring RF envelope pulse width and time of arrival data.
