Linear signal

Digital signal processing (DSP) is concerned with the representation of signals as a sequence of numbers and the algorithmic operations carried out on the signals to extract specific information contained in them. In barely 40 years the field of digital signal processing has matured considerably due to the phenomenal growth in both research and applications, and almost every university is now offering at least one or more courses at the upper division and/or firstyear graduate level on this subject. ...

Digital Signal Processing (DSP) is formally defined as a digital operation performed on an input sequence of numbers (including feedback from the result of the digital operation). The sequence of numbers can represent anything from digitised human speech to stock price data, processed to detect hidden periodicities or pattern

The implementation of active pixel based image sensors in CMOS technology is becoming increasingly important for producing imaging systems that can be manufactured with low cost, low power, simple interface, and with good image quality. The major obstacle in the design of CMOS imagers is Fixed Pattern Noise (FPN) and SignaltoNoiseRatio (SNR) of the video output.

Linear Prediction Modelling of Speech Linear predictive models are widely used in speech processing applications such as low–bit–rate speech coding in cellular telephony, speech enhancement and speech recognition. Speech is generated by inhaling air into the lungs, and then exhaling it through the vibrating glottis cords and the vocal tract. The random, noiselike, air flow from the lungs is spectrally shaped and amplified by the vibrations of the glottal cords and the resonance of the vocal tract.

We wish to construct a system which possesses socalled associative memory. This is definable generally as a process by which an input, considered as a “key”, to a memory system is able to evoke, in a highly selective fashion, a specific response associated with that key, at the system output. The signalresponse association should be “robust”, that is, a “noisy” or “incomplete” input signal should none the less invoke the correct response—or at least an acceptable response. Such a system is also called a content addressable memory....
