We showed in Part I of this paper [1] that the estimation of the white-phase noise level of a sampled signal may be achieved with variances even if the sampling frequency is far lower than the high cut-off frequency. In Part II, the effects of spectral aliasing for the different types of noise are reviewed. The responses of the Allan variance and the modified Allan variance for high-frequency n...

Aliasing is the key problem that makes reasoning about reference structures hard. Large predicates have to be constructed that capture all aliasing properties of a given state. Instead of deducing the aliasing properties from a state that uses heaps and objects, we declare the alias-relation to be the state itself. We explore if such a state model provides a new and beneficial approach to the v...

The aliasing that results in a variable being known by more than one name has greatly complicated efforts to derive data flow information. The approach we take involves the use of a series of claims that, after we compute the data flow for some of the aliasing possibilities, allows us to produce good approximations for the remaining cases. The method can thus limit the potential combinatorial e...

Subband adaptive filters have been proposed to avoid the drawbacks of slow convergence and high computational complexity associated with time domain adaptive filters. Subband processing introduces transmission delays caused by the filter bank and signal degradations due to aliasing effects. One efficient way to reduce the aliasing effects is to allow a higher sample rate than critically needed ...

Several lines of evidence are provided indicating that our visual percept can be dominated by spatial aliasing for viewing conditions near those needed to see the spatial frequency doubled illusion. The apparent aliasing effect indicates that the underlying sampling array has a density 15-30% of that of M-cells, in agreement with the known proportion of Y-like M-cells (M(y)-cells). The presence...

Spatial sound reproduction systems with a high number of loudspeakers are increasingly being used. Wave field synthesis is a reproduction technique using a high number of densely placed loudspeakers (secondary sources). The underlying theory, however, assumes a continuous distribution of secondary sources. Loudspeakers placed at discrete positions imply a spatial sampling process that may lead ...

Aliasing is quite powerful, but difficult to control. Often clients need exclusive access to objects for some concerns, and sometimes we see no other way than to ensure this by controlling aliasing. Instead, we propose to restrict what clients can do when accessing objects. To invoke methods in an object clients need tokens issued by this object. Static type checking enforces the tokens to be a...

Micro-Doppler, induced by micro-motion of targets, is an important characteristic for target recognition once extracted via parameter estimation. However, micro-Doppler is usually too significant to result in aliasing in the terahertz band. According to this problem, a Doppler aliasing free micro-motion parameter estimation method based on the modulo Generalized Hough transform is proposed in t...

A novel method for aliasing detection and resolving in the estimation of polynomialphase signal (PPS) parameters is presented. Aliasing is detected using two high-order ambiguity functions (HAFs) of a uniformly sampled PPS embedded in noise. If aliasing occurred, we propose a way of recovering the true parameters from their aliased positions. To that end, a closed-form expression for the true p...
