The Cycle 5 design baseline for the Wide-Field Infrared Survey Telescope Astrophysics Focused Telescope Assets (WFIRST/AFTA) instrument includes a single wide-field channel (WFC) instrument for both imaging and slit-less spectroscopy. The only routinely moving part during scientific observations for this wide-field channel is the element wheel (EW) assembly. This filter-wheel assembly will have...

Revised Abstract The position-variable model [R.] is extended to describe the subjective lateral position of amplitude-modulated tones and bandpass noise, as well as other complex stimuli that are presented within spectral regions at which the binaural system appears to be unable to make use of cycle-by-cycle interaural temporal differences. Predictions of the model are based on the centroid of...

It is well known that second order lowpass interpolative sigma delta modulators (SDMs) may suffer from instability and limit cycle problems when the magnitudes of the input signals are at large and at intermediate levels, respectively. In order to solve these problems, we propose to replace the second order lowpass interpolative SDMs to a specific class of second order bandpass interpolative SD...

This document describes how we correct the bandpass in the OnLine Application Processing pipeline (better known as " the Blue Gene/P correlator ").

The design of the interdigital bandpass filter annular shape with increased frequency selectivity due to convergence input and output lines introduction additional between them is suggested. This allows amplitude-frequency characteristic such a be formed attenuation poles on edges its bandpass, which significantly increases steepness slopes. A model four-resonator made results experimental inve...

Based on different sampling theorem, for example classic Shannon’s sampling theo-rem and Papoulis’ generalized sampling theorem, signals are processed by the sam-pling devices without loss of information. As an interface between radio receiverfront-ends and digital signal processing blocks, sampling devices play a dominantrole in digital radio communications.Under the concep...

We demonstrate optical 2R regeneration in an integrated silicon device consisting of an 8-mm-long nanowaveguide followed by a ring-resonator bandpass filter. The regeneration process is based on nonlinear spectral broadening in the waveguide and subsequent spectral filtering through the ring resonator. We measure the nonlinear power transfer function for the device and find an operating peak po...

Compact selective bandpass filter, based on the Rhodes approximation, is proposed using the novel modified hairpin resonators realized on a double-sided microstrip. The equivalence is presented between the hairpin resonator realized on a singlesided microstrip and the modified hairpin resonator realized on a double-sided microstrip. The footprint area of the filter is reduced by 50% with the mu...
