چکیده

An analysis of quantisation noise of multiresolution structure of analog-to digital converters (ADC) is performed. It shows how the noise level as well as the resulting noise spectrum is changing with a level of sampled signal. The theoretical formulas are approved by numerical simulation and experimental measurements performed by PC measuring card emulating two channels ADC structure. The results confirm that resulting quantization noise level is strongly dependent upon the amplitude of measured signal.

Time-Mode Signal Quantization for Use in Sigma-Delta Modulators

The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...

Decrease in Hardware Consumption and Quantization Noise of Digital Delta-Sigma Modulators and Implementation by VHDL

A new structure is presented for digital delta-sigma modulator (DDSM). Novel architecture decreases hardware consumption, output quantization noise and spurs in Comparison to previous architectures. In order to reduce the delay, power consumption and increase maximum working frequency, the pipelining technique and the carry skip adder are used. Simulation proposed architecture shows that the qu...

EVLA Memo. 88 Quantization Noise

In receiving systems in which the analog signal voltage is sampled and quantized to allow further processing in digital form, the difference between the analog samples and their digital representation gives rise to a component of random quantization noise. The power spectrum of the quantization noise is close to being uniformly level across the receiver passband, even for large variation in the...

A wideband speech coder based on harmonic coding at 16KBS

In this paper, we present an improved harmonic coder for the wideband. In an effort to improve spectrum modelling with harmonic representation, we include in the structure, a post error spectrum modelling that is essentially useful for noisy signals or mixed spectra of high pitch voices. The bit constrained error spectrum modelling procedure coupled with an efficient quantization of the harmoni...
