TL;DR: In this article, an analog of the Whittaker-Kotel-nikov-Shannon theorem on the basis of the harmonic Fourier-Bessel analysis was obtained, where generalized Bessel translations are used instead of the usual translations.
Abstract: In this paper, we obtain an analog of the Whittaker-Kotel’nikov-Shannon theorem on the basis of the harmonic Fourier-Bessel analysis. We construct a new interpolation formula for a class of entire functions of exponential type in which generalized Bessel translations are used instead of the usual translations.

07 Feb 2008TL;DR: In this paper, a gain clamping approach is used to flatten the gain of erbium doped fiber amplifier (EDFA), so that it could be used for long haul wave length division multiplexing (WDM) communication system to maximize the transmission distance.
Abstract: In this paper a gain clamping approach is used to flatten the gain of erbium doped fiber amplifier (EDFA), so that it could be used for long haul wave length division multiplexing (WDM) communication system to maximize the transmission distance. The gain clamping is done through filters like Multi-stage Lorentzian filter, Super Gaussian filter, Bessel filter, and Raised cosine filter with bandwidth of 500 GHz at center frequency 193.41 THz. It has been inferred from the simulation results that first order notch type super Gaussian filter is most appropriate for the transmission of 16 times 40 Gb/s WDM optical DPSK data with channel spacing 200 GHz, over 518 km. The quality factor obtained for all the channels is above 15 dB.

Abstract: A continued fraction expansion different from that in the Bessel filter brings a novel analog FIR filter. The circuit block including a delay component is composed of only passive elements and provides wideband signal processing. Element values are explicitly expressed without a parameter of the degree of approximation. This building block is utilized in FIR filter design together with transconductors. Design example shows that the proposed scheme reduces the circuit area.

TL;DR: In this paper, a generalization of the squared Bessel process with real nonnegative parameter δ by introducing a predictable almost everywhere positive process γ(t, ω) into the drift and diffusion terms is discussed.
Abstract: We discuss a generalization of the well known squared Bessel process with real nonnegative parameter δ by introducing a predictable almost everywhere positive process γ(t, ω) into the drift and diffusion terms. The resulting generalized process is nonnegative with instantaneous reflection at zero when δ is positive. When δ is a positive integer, the process can be constructed from δ-dimensional Brownian motion. In particular, we consider γt = Xt−τ which makes the process a solution of a stochastic delay differential equation with a discrete delay. The solutions of these equations are constructed in successive steps on time intervals of length τ . We prove that if 0 < δ < 2, zero is an accessible boundary and the process is instantaneously reflecting at zero. If δ ≤ 2, lim inft→∞Xt = 0. Zero is inaccessible if δ ≥ 2.

TL;DR: A novel Equalizer-Driver that combines equalizing and driving functionalities in a single function aimed at increasing the bandwidth and energy efficiency of electro-optical (E/O) transmitters is introduced.
Abstract: This paper introduces a novel Equalizer-Driver that combines equalizing and driving functionalities in a single function aimed at increasing the bandwidth and energy efficiency of electro-optical (E/O) transmitters. Implemented in III-V Lab’s 0.7-µm InP DHBT technology, the Equalizer-Driver exhibits in full EM-circuit co-simulation 13 dB of differential gain (S d2d1 ) at 10 MHz and 16 dB of peaking gain at 55 GHz, for a total intrinsic -3 dB-bandwidth over 100 GHz. Transient simulations show it is able to provide an equalized and amplified 3.7-V pp diff linear output signal in PAM4 at 64 GBd, from an input signal filtered by a Bessel filter with a 17-GHz -3 dB-bandwidth. Consuming 1.2 W at its maximum 3.7-V pp diff linear output swing, it is well suited for bandwidth limited optical transmitters at 64 GBd and beyond.
