چکیده
EEG contains a wealth of physiological, psychological and pathological information, EEG signal analysis and processing are either in clinical of some brain disease diagnosis and treatment, or in the cognitive science research fields are very important. According to the basic characteristics of EEG signal, discusses the EEG signal acquisition principle, method and the design train of thought. Proposed pre-amplification system design, after prestage processing of EEG signals, can be seen in the EEG signals transform trend, coupled with the follow-up processing, can get the clear stability of EEG signal, and has good application value.

One of the important issues in designing a brain-computer interface system is to select the type of mental activity to be imagined. In some of these systems, mental activity varies with user intent and action that must be controlled by the brain-computer system, and in a number of other signals, the received signals contain the same activity-related mental activity that should be performed by t...

Brain-computer interfaces (BCI) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. These systems do not use normal neuromuscular output pathways. Actually, the principal goal of BCI systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic l...

متن کاملAn Optical-Electrical Sub-Sampling Down-Conversion Receiver with Continuous-Time EA Modulation
This thesis describes the design and implementation of an optical-electrical subsampling down-conversion receiver that employs EA modulation. Accurate subsampling of an electrical RF signal in the optical domain is achieved by using a low-jitter mode-locked-laser and a high-bandwidth interferometer. The sub-sampled information is then digitized by an optical-electrical continuous-time (CT) EA a...
