DSP (Digital Signal Processing) decimation and interpolation are two signal processing techniques used to change the sampling rate of a digital signal. Decimation involves reducing the sampling rate of a signal, while interpolation involves increasing the sampling rate of a signal.
DSP decimation and interpolation are commonly used in digital signal processing to reduce or increase the size of a digital signal. This can be helpful in various applications such as data compression, filtering, and resampling.
The main benefit of using DSP decimation/interpolation is the ability to manipulate the sampling rate of a digital signal without significantly altering its frequency content. This allows for more efficient storage and processing of digital signals, and can also improve the quality of a signal in certain applications.
DSP decimation and interpolation both involve using mathematical algorithms to alter the sampling rate of a digital signal. Decimation involves removing samples from the signal, while interpolation involves inserting new samples based on the existing ones. Both techniques use filters to prevent aliasing and ensure the integrity of the signal.
DSP decimation/interpolation is commonly used in audio and video processing, as well as in wireless communication systems. It is also used in data compression, image processing, and other digital signal processing applications where the sampling rate needs to be adjusted without altering the signal's characteristics.
