Zero-padding is a technique used in signal processing where zeros are added to the beginning and/or end of a signal to increase its length. This process is essential in preparing signals for operations like the Fast Fourier Transform (FFT) and helps prevent spectral leakage by ensuring that the original signal fits more neatly into the new time window. Additionally, zero-padding can facilitate better interpolation and decimation processes, making it easier to manipulate signals without losing important information.
congrats on reading the definition of zero-padding. now let's actually learn it.
