In this article we consider transient random walks on free products of graphs. We prove that the asymptotic range these exists and is strictly positive. particular, show varies real-analytically in terms probability measures constant support. Moreover, a central limit theorem associated with walk.

In this paper we introduce an offline digital calibration technique that allows the feed-forward residue compensation (FRC) architecture to provide a 70-Msps 15-bit converter with a final spurious-free dynamic range (SFDR) of over 100dB. We develop analytical expressions for the maximum accuracy that can result from this architecture. Simulations of the overall architecture including device mis...

We report the design, fabrication and characterization of a balanced optical discriminator for a high performance phase modulation-direct detection microwave photonic link (MPL). The discriminator is an integrated optical filter consisting of five ring resonators which are fully tunable using thermo-optical tuning. The discriminator is configured to yield a desired transfer where the intensity ...

This paper presents an efficient technique to extremely increase the performance of Pedersen’s digital chirp generator concerning the level of the Spurious-Free Dynamic Range (SFDR) and size of the memory. The proposed digital chirp generator uses the piecewise parabolic interpolation to decrease the memory size and system complexity while maintaining excellent spectral performance in compariso...

This paper addresses the problem of improving the spurious free dynamic range (SFDR) for digitization by use of antenna arrays. Nonlinearities in the analog-to-digital conversion process give rise to spurious signals (harmonics and intermodulation products) that limit the overall SFDR of the digitization process. When the signal of interest arises from a sensor such as an antenna or hydrophone,...
