Low Power Medical Signal Processing
Many medical and fitness applications can benefit from digital signal processing that is well within the capabilities of
inexpensive, low-power processors, including the processing of signals from phonocardiography (stethoscopes),
electrocardiography (EKGs), and electroencephalography (EEGs). Types of processing include noise reduction, signal
analysis and display, signal separation and filtering, and processing for newly-developed sensors such as MEMS
accelerometers. In addition to clinical usage, inexpensive, low-power signal processing can help people stay healthy by
monitoring heart rate and respiration during exercise and body motion while running and going about daily life. This talk will
describe signal processing for digital stethoscopes, robust heart rate detection for fitness equipment, detection of seizure
onset for implants, and monitoring vital signs and body motion using a 3-axis MEMS accelerometer.

Since joining Texas Instruments in 1995, Dr. Cole has managed digital audio and multimedia
R&D at TI, represented TI in industry associations and forums, and helped establish TI’s
portable audio business groups. He was elected a Distinguished Member, Technical Staff in
2001. He is currently consumer electronics co-chair for the Copy Protection Technical Working
Group, a multi-industry discussion group. Dr. Cole received a PhD in Electrical Engineering &
Computer Science from the University of Utah in 1972, and has worked in the areas of digital
audio, speech coding, video coding, and geophysical signal processing. As a project leader at
the University of Southern California’s Information Sciences Institute, he led a group that did
pioneering work in packet voice and packet video. In 1975, he co-founded Soundstream, the
first US digital audio recording company. Dr. Cole also worked as a principal systems engineer
for Citicorp/TTI, where he developed advanced technology for financial transaction terminals,
and later directed speech research for Echo Audio, where he developed a speech
coder for Internet applications. He is a member of IEEE and the AES.
