TL;DR: In this article, the transmitter has an optical p-i-n type interferometric structure with two branch sections (Ba,Bb) and a control voltage is applied to each section by a control circuit, which is formed by addition of a constant voltage and an additional voltage produced from the input electrical signal which is pass band filtered.
Abstract: The transmitter has an optical p-i-n type interferometric structure (1) with two branch sections (Ba,Bb). A control voltage is applied to each section by a control circuit (2). The control voltages are formed by addition of a constant voltage and an additional voltage (ea) produced from the input electrical signal which is pass band filtered. The filter is preferably a Bessel filter and the branch sections are formed from waveguide sections with the same structure but different lengths.
TL;DR: In this article, a method for the calculation of Bessel functions of the first kind of integral order was proposed by using the Laplace transformation, and a linear differential equation was solved to define the generating function for the Bessel function expressed in terms of continued fractions.
Abstract: We propose a new method for the calculation of Bessel functions of the first kind of integral order. By using the Laplace transformation, we solve a linear differential equation that defines the generating function for the Bessel functions expressed in terms of continued fractions.
TL;DR: In this article, the m th positive zero of J n (x ) (n not necessarily integral) was shown to be a positive zero, and it was conjectured from numerical considerations that Relton (1, p. 59) conjectured that
Abstract: Let j nm be the m th positive zero of J n ( x ) ( n not necessarily integral). Then Relton (1), p. 59, has conjectured from numerical considerations that

TL;DR: This proposed CORDIC based VLSI architecture is suitable to use before FFT for real time digital spectral analysis system and also can be used for filtering applications to compute Kaiser-Bessel window coefficients and the error analysis has been discussed.
Abstract: In this paper, proposed CORDIC based VLSI architecture for implementing Kaiser-Bessel Window. This proposed architecture is suitable to use before FFT for real time digital spectral analysis system and also can be used for filtering applications to compute Kaiser-Bessel window coefficients and the error analysis has been discussed. The proposed architecture has synthesised in Synopsys design compiler (Design Vision) using TSMC 90 nm technology library.
