ADC's effective bits specification provided the overall measure of system performance. The errors produced in ADC due to quantization were also measured. Th... G. Lang - 《Sound & Vibration》 被引量: 4发表: 2000年 Chapter 2 in Delta-sigma Data Converters Quantization Noise in A/d ...
The post converter filter therefore filters out a portion of the larger quantization noise when the digital amplitude is larger. Quanitization noise is reduced without limiting the input signal voltage range that can be digitized.doi:US7068197 B1Anatoliy V. Tsyrganovich...
This paper focuses on the detection and quantification of three types of noise, analog-to-digital converter (ADC) clipping, quantization noise, and amplifier saturation, in surface electromyography (sEMG) without prior information regarding the sEMG setup. ADC clipping can be detected by searching for...
The signal-to-noise ratio (SNR) of an ADC is the ratio of the signal power to the non-signal power. Non- signal power includes thermal noise, quantization noise, and other residual errors in the converter, measured in the Nyquist bandwidth (fSAMPLE/2) of the ADC. SNR is typically ...
In [11] the quantization noise and dynamic range are considered for compressive imaging (CI) systems design and evaluate the quantization depth requirements for CI, while the quantization error and the SFDR performance of CS are still undiscussed. Effects of ADC nonlinearity on the spurious dynamic...
According to theoretics and simulation, it is proved that the ICR is barely influenced and the loss of output SNR is less than 0.1 dB when the quantization interval equals to 0.5sigma (sigma is the RMS of the ADC input thermal noise). 展开 ...
We analytically quantify the introduced distortion as a function of bit resolution and clipping ratio, both at the DAC and ADC. With this we provide a back-to-back signal-to-noise ratio analysis to predict the bit error rate of the system, assuming a fixed received optical power and ideal ...
The signal-to-noise ratio (SNR) of an ADC is the ratio of the signal power to the non-signal power. Non-signal power includes thermal noise, quantization noise, and other residual errors in the converter, measured in the Nyquist bandwidth (fSAMPLE/2) of the ADC. SNR is typically defined...
Using coarse resolution analog-to-digital conversion (ADC) offers the possibility to reduce the complexity of digital receive systems but introduces a loss in effective signal-to-noise ratio (SNR) when comparing to ideal receivers with infinite resolution ADC. Therefore, here the problem of signal ...
In a space-borne azimuth multi-channel SAR system, thermal noise will be generated during the operation of each channel receiver. The radar echo signal received by each channel receiver will be superimposed with the thermal noise generated by the corresponding channel receiver as radar echo data ...
