Description: This example solves a 2nd order wave equation: utt = uxx + uyy, with u = 0 on the boundaries. It uses a 2nd order central finite difference in time and a Chebyshev spectral method in space (using FFT). It compares to running the same algorithm on the GPU using gpu-arrays and built-in functions available for the GPU.

Description: DSPLab is a library of delphi components for digital signal processing. The library contains two components: IIR Filter and FFT. IIR Filter is Butterworth, Bessel and Chebyshev infinite-impulse-response (IIR) filters, with lowpass, highpass, bandpass or bandstop characteristics. You can build the filter of first order, filter of second order, and so on. The maximal order of filter is eight. The FFT component implements Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT).
