The Sinc-Galerkin method originally proposed by Stenger is extended to handle fourth-order ordinary differential equations. The exponential convergence rate of the method, $\mathcal{O}(e^{-\kappa\sqrt ...
In “Why DAC and ADC responses droop,” we looked at the two common places where the sinc() function crops up in a data acquisition system. A DAC with zero-order hold has a frequency response that ...
