A small introduction to the applications DSP focussing on how ECG signal  is obtained.

1. DIGITAL SIGNAL
PROCESSING
BY
ABHIRAM

2. SIGNAL
PROCESSING:
Analysis interpretation
and manipulation of like
sound, images, time
varying measurement
values and sensor data.
Types
Analog signal processing
Digital signal processing

3. Digital Signal Processing applications.
Digital filtering
Spectral analysis
Speech processing
Image processing
Radar and sonar processing

4. Medical Field
• MRI scan,
• X-Ray Scans,
• PET- Positron Emission Tomography
• Electrocardiography (ECG)
• cellular motion tracking,
• laparoscopic scanning,
• Computerised Tomography (CT) scans,
• Ultra sound.
• Nuclear Medicine Imaging.

5. ECG
Electrocardiogram
 Simple test that can be used to check your
heart’s rhythm and electrical activity.
 Measures electrical activity of the heart to
detect cardiac problems.

6. ECG
{electrocardiogram}
STEPS
• ELECTRODES PLACED ON SKIN
• PACEMAKER CELLS FIRE UP
• SIGNALS CONDUCTED VIA THE
BODY TISSUES
• RAW SIGNALS PICKED UP BY THE
ELECTRODES PLACED ON THE
SKIN
• RAW SIGNALS CONTAIN NOISE
• FILTERED BY PASSING VIA HIGH
PASS FITER
• INTERPRETED AS A GRAPH ON A
SCREEN
• EXPERT ANALYSIS AGAINST THE
NORMAL SIGNAL.
