A method of quantized monotonie denoising and the rnultiscale analysis are proposed with two criterions to evaluate the inversion accuracy enhanced by data processing.

An analysis of quantization noise in FM transmitter at intermediate offset frequencies;

Quantization noises of three types of Σ-Δmodulators are analyzed based on a linearized model'By using signal flow graphics method,each transfer function,quantization noise and quantization signal-to-noise ratio(SNR) is derived respectively.

Quantization noise in AD conversion will influence bias stability of FOG.

Then the variance of quantification noise and SNR loss are compared between minimization quantification and uniform quantification for the same conditions.

Based on the study of the influence of the quantification noise and the gray level noise on target feature image,the error model of the target feature image centroid coordinates is built.

In this paper,the formula of ranging MSE root of multiple frequency CW radar is concluded when the quantification noise is considered.

In the system,the reference signal is processed by the attenuator and the phaser before sampling to cancel the direct signal from the received antenna,so that the quantizing noise power is reduced and the detection capability is enhanced.

By comparing the ternary and the binary encoded delta-modulation system we can find that the quantizing noise of ternary encoded delta-modulation system is lower and the lower power dissipation is its another virtue.
