TL;DR: In this paper, a technique for the design of a recursive digital filter with maximally flat responses in both magnitude and group delay was proposed, and the results showed that the resulting filter always showed smooth responses no matter what the difference is in the polynomial degrees of the numerator and denominator.
Abstract: A technique is proposed for the design of a recursive digital filter with maximally flat responses in both magnitude and group delay. In comparison to the previous designs [1]-[3], the magnitude and group delay always show smooth responses no matter what the difference is in the polynomial degrees of the numerator and denominator.

TL;DR: In this paper, an orthogonalized Fourier method for numerical evaluation of oscillatory integrals which have an infinite range of integration was presented, attaining maximum efficiency in the limit of rapid oscillations.
Abstract: : The authors present an orthogonalized Fourier method for the numerical evaluation of oscillatory integrals which have an infinite range of integration. This method in contrast to others which have been developed, attains maximum efficiency in the limit of rapid oscillations. The results are compared to those obtained from a Gaussian integration scheme and the Shanks acceleration of the Gaussian results. Special attention is given to the evaluation of the modified Bessel Function (K sub i, zeta) (x).

TL;DR: In this article, the performance analysis of 10Gbps optical receiver for fiber optical link is presented, where non-return to zero (NRZ) electrical signals from a pseudo-random bit sequence (PRBS) generator are used as modulation input.
Abstract: In this report, the performance analysis of 10Gbps optical receiver for fiber optical link is presented. Non-Return to Zero (NRZ) electrical signals from a Pseudo-Random Bit Sequence (PRBS) Generator are used as modulation input. Signals in the optical domain are detected at the PIN photodiode (PIN-PD) and are converted into electrical output signals. These electrical signals are filtered through a low pass bessel filter. Effects of bandwidth and thermal noise of receiver on the link performance are studied in detail. For the 10Gbps fiber optical communication, a Q factor of 6.55 and the BER of 5.23E?11 are observed for the worstcase, when the receiver is operated at 100°C. it is shown that BER heavily depends on thermal noise. The relation between the receiver sensitivity and the thermal noise is also investigated.

TL;DR: A new optical burst signal receiver that uses the transfer function, Gn (s) =1-Hn (s), where Hn(s) denotes a Bessel filter transfer function of order n, and it has better performance than the conventional AC-coupling one.
Abstract: To realize economical optical burst signal receivers for the Optical Network Unit (ONU) of the Ethernet Optical Switched Access Network (E-OSAN), we previously implemented optical burst receivers with AC-coupling and DC-coupling using off-the-shelf components, and showed that the former offers better performance. This paper proposes a new optical burst signal receiver that uses the transfer function, Gn(s) =1-Hn(s), where Hn(s) denotes a Bessel filter transfer function of order n. We also present a method for designing the proposed receiver and clarify that it has better performance than the conventional AC-coupling one. We then present an LCR circuit synthesis of Gn(s), which is necessary to actually implement a burst receiver based on the proposal.

TL;DR: These zeros are first computed numerically through an implementation of the electrostatic interpretation formulas and then a fit to the real and imaginary parts as functions of , and it is shown that the resulting complex number is -convergent to for fixed .
Abstract: We find approximate expressions and for the real and imaginary parts of the th zero of the Bessel polynomial . To obtain these closed-form formulas we use the fact that the points of well-defined curves in the complex plane are limit points of the zeros of the normalized Bessel polynomials. Thus, these zeros are first computed numerically through an implementation of the electrostatic interpretation formulas and then, a fit to the real and imaginary parts as functions of , and is obtained. It is shown that the resulting complex number is -convergent to for fixed .
