Lesson 1 Introduction
- What is electronics?
Science and technique of directing electrons(or any other charge carriers) to perform useful functions
- Electronic devices for directing electrons:
- Directing electrons- Apply potential difference Voltage (V)
- Flow of electrons Current (I)
Resistor (R), Capacitor (C), Inductor (L)
Diode, Transistor
- Useful functions by electronic devices
- Amplification, Filtering, Sampling ....
- Analog, Digital

Lesson 1 Introduction
Why study electronic circuits?
- Semiconductor industry is very important for us:
- Korean semiconductor exports in 2013:10.2% of the total export, 8.2% of GDP
- 2013 market share by sales for Korean semiconductor industry: 15.8%, Second to US
- Electronic circuits are the basic building block for electrical/electronic engineering
