Lecture

Reconstruction: Undersampling and Filtering

Description

This lecture discusses the effect of undersampling on signals, particularly the stroboscopic effect, and presents a solution involving filtering the signal before sampling to avoid this effect. By using an ideal low-pass filter and interpolation, the signal can be reconstructed perfectly without the stroboscopic effect.
