Along with distortion, we use Signal to Quantization Noise Ratio for the performance estimation [1]-[3]
More distinctively, transmitter and receiver non-linearities, phase noise, receiver quantization noise, receiver Gaussian noise and channel estimation problems are also accounted.
where the [sigma] is the standard deviation of quantization noise, and the noise gain C is set to be 1.
In contrast to the backward adaptation technique, forward adaptation provides gain in Signal to Quantization Noise Ratio (SQNR) in the wide dynamic range [18], as well as less sensitivity to transmission error [2]; however, it requires transfer of side information to the receiving part.
However, during the operation of the FOG, there are a large number of random noises in the gyro signal, such as quantization noise, angle random walk, and bias instability [11].
Due to TDC finite resolution, it introduces quantization noise on the output of synthesizer spectrum.
An Agilent Technologies application note explained, "ENOB is reduced by all the noise and error sources in the oscilloscope including ADC quantization noise, ADC differential nonlinearity (DNL), ADC integral nonlinearity (INL), thermal noise, shot noise, and input amplifier distortion.
One way to achieve further reduction of quantization noise is to use a multibit quantizer only in the final stage to eliminate the necessity of DEM techniques to improve the linearity of multibit DAC.
The quantization noise generated by the AZ modulator is visible between 1 and 7 MHz away from the carrier.
Simulations made for a sampling voltmeter showed that the errors in the measured rms amplitude have a non-normal probability distribution, such that the probability of large errors is much greater than would be expected from the usual quantization noise model.
