- Apr 23, 2026 Bilinear Weighting and the Tent Reconstruction Filter How four texel taps and two linear interpolants reconstruct a continuous signal, why the resulting kernel is a tent, and what that kernel does to frequencies above half the texel rate. computer graphics
- Dec 29, 2022 Sampling Rate, Aliasing, and the Folding of the Spectrum Why the Nyquist criterion constrains the signal rather than the converter, how aliasing folds frequencies arithmetically, and what reconstruction actually requires. scientific computing
