ARM MCU Based Experimental EEG Signal Generator Using Internal DAC and PWM Outputs

نویسندگان

چکیده

Electrophysiological signal generators are widely used in biomedical engineering research, education and the testing of devices hospitals. Such also available commercially. The EEG (Electroencephalography) is an electrophysiological which emitted from brain. In this study, a generator that produces experimental signals taken databases proposed. proposed reads data SD card with SDIO serial protocol. addition, PWM DAC outputs microcontroller examined separately to generate signal. It has been shown database can be generated by using cheap easily accessible electronic devices.

Assessment of Anesthesia Depth Using Effective Brain Connectivity Based on Transfer Entropy on EEG Signal

Introduction: Ensuring an adequate Depth of Anesthesia (DOA) during surgery is essential for anesthesiologists. Since the effect of anesthetic drugs is on the central nervous system, brain signals such as Electroencephalogram (EEG) can be used for DOA estimation. Anesthesia can interfere among brain regions, so the relationship among different areas can be a key factor in the anesthetic process...

P81: Detection of Epileptic Seizures Using EEG Signal Processing

Epilepsy is the most common brain diseases that cause many problems in the daily life of the patient. In most attempts to automatic detection, the attack used an EEG. In this paper, The complete data set consists of five sets recorded from normal and epileptic patients. Each set containing 100 single-channel EEG segments. Here we used first and last sets (A and E). Set A consisted of segments r...

Depth of anesthesia estimation based on EEG signal using brain effective connectivity between frontal and temporal regions

Background: Ensuring adequate depth of anesthesia during surgery is essential for anesthesiologists to prevent the occurrence of unwanted alertness during surgery or failure to return to consciousness. Since the purpose of using anesthetics is to affect the central nervous system, brain signal processing such as electroencephalography (EEG) can be used to predict different levels of anesthesia....

An Arbitrary Chaos Generator Core Circuit Using PWM/PPM Signals

A compact chaos generator core circuit has been designed, fabricated, and tested. It generates PWM and PPM (pulse width and phase modulation) signals that follow arbitrary nonlinear analog dynamics. The measurement results show that PWM/PPM chaotic signals are generated at 1 MHz with a calculation precision of 6.7 bits at a supply voltage of 3.3 V. The circuit can be used for large-scale integr...
