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 ...
As it carries the information, the chaotic signal is also called chaotic carrier. Synchronizing these oscillators is similar to synchronizing random neural nets in neural cryptography. When chaos synchronization is used, a basic scheme of a communications device (Cuomo and Oppenheim 1993) is made by two identical chaotic oscillators. One of ...
Nonlinear signal processing involves the analysis and processing of signals produced from nonlinear systems and can be in the time, frequency, or spatiotemporal domains. [8] [9] Nonlinear systems can produce highly complex behaviors including bifurcations, chaos, harmonics, and subharmonics which cannot be produced or analyzed using linear methods.
S. Hamid Nawab [1] is Professor of Electrical and Computer Engineering and Biomedical Engineering at Boston University who is a researcher, educator, and engineer in the signal processing and machine perception subfields of Electrical Engineering and their application to the machine/computer analysis of complex biosignals from auditory, speech, and neuromuscular systems.
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 ...

In both cases, the dominant component is at the signal frequency: = / =. Also visible in Fig 2 is the spectral leakage pattern of the L = 64 {\displaystyle L=64} rectangular window. The illusion in Fig 3 is a result of sampling the DTFT at just its zero-crossings.
