BME 4710 - Biomedical Instrumentation II

2 lecture hours 3 lab hours 3 credits
Course Description
This course introduces the fundamentals of several biological signals, e.g., ECG, EMG, and EEG. The course also introduces electrodes and electronic amplifiers needed to acquire them. Methods for reducing electrical noise and electromagnetic interference in the signals, and conversion between analog and digital forms are included.
Prereq: BME 3710 , ELE 3300  (quarter system prereq: BE 3705)
Note: None
This course meets the following Raider Core CLO Requirement: None
