    Understanding Digital Signal Processing. Prentice Hall. p. 304. ISBN 0-201-63467-8. Decreasing the sampling rate is known as decimation. Antoniou, Andreas (2006). Digital Signal Processing. McGraw-Hill. p. 830. ISBN 0-07-145424-1. Decimators can be used to reduce the sampling frequency, whereas interpolators can be used to increase it.

  3. DSP-4 - Wikipedia

    en.wikipedia.org/wiki/DSP-4

    DSP-4, or N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine, is a monoaminergic neurotoxin selective for noradrenergic neurons, capable of crossing the blood–brain barrier. [1] It exerts transient effects in peripheral sympathetic neurons, but more permanent changes within neurons of the central nervous system. It can induce long-term depletion in ...

    en.wikipedia.org/wiki/Digital_signal_processing

    Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...

  5. Digital signal processor - Wikipedia

    en.wikipedia.org/wiki/Digital_signal_processor

    A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. [ 1 ] : 104–107 [ 2 ] DSPs are fabricated on metal–oxide–semiconductor (MOS) integrated circuit chips.

  6. Unfolding (DSP implementation) - Wikipedia

    en.wikipedia.org/wiki/Unfolding_(DSP_implementation)

    [1] [2] Unfolding in general program is as known as Loop unrolling. Unfolding has applications in designing high-speed and low-power ASIC architectures. One application is to unfold the program to reveal hidden concurrency so that the program can be scheduled to a smaller iteration period, thus increasing the throughput of the implementation.

  7. Digital down converter - Wikipedia

    en.wikipedia.org/wiki/Digital_down_converter

    In digital signal processing, a digital down-converter (DDC) converts a digitized, band-limited signal to a lower frequency signal at a lower sampling rate in order to simplify the subsequent radio stages. The process can preserve all the information in the frequency band of interest of the original signal.

    Alan Victor Oppenheim [2] (born 1937) is a professor of engineering at MIT's Department of Electrical Engineering and Computer Science. He is also a principal investigator in MIT's Research Laboratory of Electronics (RLE), at the Digital Signal Processing Group. His research interests are in the general area of signal processing and its ...

  9. Linear predictive coding - Wikipedia

    en.wikipedia.org/wiki/Linear_predictive_coding

    Linear predictive coding (LPC) is a method used mostly in audio signal processing and speech processing for representing the spectral envelope of a digital signal of speech in compressed form, using the information of a linear predictive model.
