The leaky integrator: Denoising and impulse response

This lecture introduces the concept of the leaky integrator, a first-order recursive filter used for denoising signals. The instructor explains how the leaky integrator works, its impulse response, and why it is named as such due to its ability to prevent signal 'explosion' by retaining only a fraction of the accumulated value. Through examples and mathematical derivations, the lecture illustrates the application of the leaky integrator in signal processing.
