This article describes a four-channel amplifier for human neurophysiologic electrical activity measurement. The advantage of the device, in combination with the developed software, lies in the real-time display of various human electrical signals such as ECG, EEG and EOG. Signal samples are stored in a binary file on the hard drive for further analysis. Combination of leads is changeable depending on the measurement type and characteristics thereof. Gain of individual leads is adjustable by digital potentiometers. The various types of measurement are presented in the article in order to verify device function.
