Technological Basics of EEG Recording and Operation of Apparatus

Emotion is a multimodal entity. It can be recognized by analyzing brain and speech signals generated by emotions. This chapter reports on methods of acquiring brain and speech signals using noninvasive techniques, and describes in detail the RMS EEG 32-channel electroencephalography (EEG) machine which is commonly used in medical and research applications. The chapter presents key aspects of EEG imaging technology. Speech signals can be acquired and analyzed by many commercially available types of equipment, including Computerized Speech Laboratory (CSL) which is described in the chapter. The chapter serves as a resource for the fundamentals of EEG and speech processing equipment.
