<p>In general, the noise shaping responses, a cyclic second order response is delivered by method of data weighted averaging (DWA) in which output digital-to-analog convertor (DAC) restricted to one two states. DWA works efficiently for rather low levels quantizing; it begins presenting considerable difficulties when internal quantizing are extended further. Though, each added bit causes ...
A critical survey has been conducted on high energy-efficient bidirectional converters, various topologies that effectively meet the automated vehicle requirements, and 24 GHz/77 GHz low-profile antennas (for automotive radar applications). The present identified into two parts current topic of study as perspectives challenges. Part 1 this covers power electronic convertor condition monitoring ...
We propose a simple and cost-effective method, using direct frequency modulation (FM) noncoherent detection (NCD) scheme, to suppress the nonlinear optical effects in dense wavelength division multiplexed (DWDM) communication. The FM transmitter comprises directly modulated distributed feedback laser saturable semiconductor amplifier. In NCD receiver, an slope filter as intensity (IM) signal co...
In the paper, the geometrical parameters and energetics of the extremely narrow pseudo-nondiffracting beams with the spot size of several micrometers are examined. The main attention is focused on design, realization and testing of the set-up enabling conversion of the laser diode beam or the fiber mode to the narrow Bessel-Gauss beam whose spot can be continuously relocated across the plane pe...
