Digital signal processing
Digital signal processing (DSP) is the mathematical manipulation of an information signal to modify or improve it in some way. It is characterized by the representation of discrete time, discrete fre...
New Technique Captures The Activity Of An Entire Brain In A Snapshot
When it comes to measuring brain activity, scientists have tools that can take a precise look at a small slice of the brain (less than one cubic millimeter), or a blurred look at a larger area. Now, r...
New Imaging Technique May Find Real Alzheimer's Culprit
PET scans that highlight the tangle-causing protein tau may better predict memory loss of Alzheimer's than older methods, researchers say.

Time domain
Time domain is the analysis of mathematical functions, physical signals or time series of economic or environmental data, with respect to time. In the time domain, the signal or function's value is k...
Frequency domain
In electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency, rather than time. Put simply, ...
Data compression
In digital signal processing, data compression, source coding,or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either lossy or...
Error detection
In information theory and coding theory with applications in computer science and telecommunication, error detection and correction or error control are techniques that enable reliable delivery of dig...
Audio signal processing
Audio signal processing, sometimes referred to as audio processing, is the intentional alteration of auditory signals, or sound, often through an audio effect or effects unit. As audio signals may be ...
Speech processing
Speech processing is the study of speech signals and the processing methods of these signals. The signals are usually processed in a digital representation, so speech processing can be regarded as a s...
Image processing
In imaging science, image processing is any form of signal processing for which the input is an image, such as a photograph or video frame; the output of image processing may be either an image or a s...
