Indian Journal of Physiology and Pharmacology. 1995 Oct; 39(4): 389-94http://imsear.searo.who.int/handle/123456789/108567A data acquisition system--using self designed and assembled A/D and D/A converter board and appropriate software--has been developed for the International Business Machine (IBM) Personal Computer and has been used for spectral analysis of bio-electric signals. Spectral analysis of EEG signals was performed and the reliability confirmed by analysis of the same data by a standard systemdeveloped by Dynalog Inc, USA. The cutting edge of the system however, lies in its extreme low cost, combined with the versatility offered due to it being a computer based system.engAutomatic Data Processing --economicsCalibrationCost-Benefit AnalysisElectrocardiography --economicsElectroencephalography --economicsHumansMicrocomputersSignal Processing, Computer-Assisted --instrumentationSoftwareJournal Article
