CEBE demonstrator:biosignals encoder

Maksim

Background

Biosignals: electrocardiogram (ECG), electroencephalogram (EEG), surface electromyogram (SEMG),

bioacoustic signals: (lung, heart, and bowel sounds)

2

Eelectroencephalogram (EEG)

0.5..60(100) Hzdownto 2-10 uV

3

Electrocardiogram (ECG)

{0.5..100; 100..1000} Hzdownto 1 uV

4

Motivation

When digitized for storage and

analysis - large amounts of data

are produced

5

Data compression

Lossless

Huffman

Arithmetic

Lempel-Ziv (.ZIP)

Lossy

JPEG

MPEG

MP3

For lossy codecs the biosignals’ properties have

to be thoroughly analyzed!

Intro-6

The idea

A biosignal encoder implementation

as a part of a system.

FPGA-based encoder
