We present the analysis of a ternary FIR filter at varying OSR (Over Sampling Ratios). The sigma delta modulated ternary filter impulse responses obtained using Matlab at varying OSRs show that each doubling of OSR results in an increase of 10dB in

Sigma-delta modulated systems have a number of very appealing properties and are, therefore, heavily used in analog to digital converters, amplifiers, and modulators. This paper presents new results which indicate that they may also have significant

The DC content in single-bit domain is both undesirable and hard to remove. In this paper we propose a single-bit multiplierless DC-blocker structure. The input is assumed to be sigma-delta modulated bitstream. This DC-blocker is designed using a del

While one-bit ΣΔ modulators are widely used in Analog to Digital conversion stages due to their inherent linearity and precision, it is less common for the entire digital processing path to operate in single bit mode at the oversampled rate of the

Adaptive bit-loading algorithms can improve the performance of OFDM systems significantly. The tradeoff between the performance of the algorithm and its computational complexity is essential for the implementation of loading algorithms. In this paper

In this work we considered the stability of a single-bit high-order sigma-delta modulator under dc input. A new approach for stability analysis is proposed. A nonlinear circle map is suggested to model the dynamics of the modulator. An analogy betwee

LMS adaptive technique is a time-varying process that, inherently, suffers from sources of colored noise due to both the nature of the algorithm itself and the practical implementation constraints. Engineers have used to postulate white noise approxi
