New bounds of Sinc function by using a family of exponential functions

Revista De La Real Academia De Ciencias Exactas, Fisicas Y Naturales - Serie A: Matematicas, 2021
The authors present new bounds for approximating the sinc function \((\sin x)/x\), where the unknown \(a_{i}\) and \(\alpha\) are determined using two-point Páde approximation. When compared to previous bounds, it achieves a much better approximation effect. A new method for proving the results is also provided.

Evaluation of reaction rate of thermogravimetric analysis data using periodic sinc function interpolation

International Journal of Chemical Kinetics
The periodic sinc function interpolation offers a compelling solution to address the issue of noise in the analysis of thermogravimetric analysis (TGA) data, thereby enhancing the outcomes of differential techniques such as the Friedman isoconversional ...

Frequency Diverse Array Beampattern Synthesis With Sinc- and Weighted-Sinc-Function-Based Frequency Offsets

IEEE Transactions on Antennas and Propagation
Frequency diverse array (FDA) has received much attention due to its capability of forming range–angle-dependent beampatterns. However, the standard FDA can only provide S-shaped beampatterns, leading to weakening the signal-to-interference-plus-noise ...
