Zero-padding is the process of adding zeros to the end (or sometimes the beginning) of a signal or data sequence to increase its length without changing its content. This technique is widely used in signal processing to ensure that the length of signals matches for operations like convolution and to improve the efficiency of algorithms such as the Fast Fourier Transform (FFT). It allows for better spectral resolution and avoids artifacts that may arise during analysis.
congrats on reading the definition of Zero-Padding. now let's actually learn it.
