## ECEN 1400 - Introduction to Digital and Analog Electronics

### Course Notes

• Atoms and Charge giving a short introduction to the atomic structure of matter and the origin of charge.
• Current, Voltage, and Power relating current to charge and voltage/power to energy.
• Schematic Diagrams and Symbols introducing schematic diagrams and schematic symbols for the most important elements. Also shows examples of typical elements used in practice.
• Ohm's Law including series and parallel connection of resistors, power rating, voltage division, and current division.
• i-v Characteristics. Relationship between current and voltage for 2-terminal devices like resistors and diodes (linear and non-linear i-v Characteristics).
• Capacitors. Introduces the most important properties and features of capacitors used in electronic circuits. Starts from the i-v characteristic of capacitors and derives series/parallel combination of capacitors, charge/discharge waveforms, capacitors with sinusoidal ac waveforms, phasors, reactance, and impedance. A video lecture using these slides is available here.
• Frequency Response of RC Circuits (updated 1-28-14). Looks at the response of RC lowpass filters (LPF) and highpass filters (HPF) in time and frequency. The system functions H(f) are derived using phasors and the magnitude and the phase of the frequency responses are computed and plotted.
• Voltage/Current Sources, Kirchhoff's Laws. Introduces properties and i-v characteristics of ideal voltage and current sources. Kirchhoff's current and voltage laws are presented and used to analyze simple circuits.
• RRC Filter system function and frequency response example and RRC Filter Video. Derivation of the system function H(f) of a RRC filter using impedances and voltage division.
• Semiconductor Diodes. Semiconductor materials with p and n doping, forward- and reverse-biased pn junction, i-v characteristic of semiconductor diodes.
• Transistors and Transistor II video. Introduction to bipolar junction transistors (BJTs). Uses current-controlled current source model as equivalent circuit for transistor. Common emitter and common base circuits are analyzed.
• Analog Electronics Concept Map. Concept map for analog electronics as covered during the first 6 weeks of class. Created on Mon. 2-24-14 in class.
• SOP and POS notes and SOP and POS video. Defines minterms and maxterms for binary logic expressions and shows how to implement logic functions specified by truth tables using sum of products (SOP) and product of sums (POS) Boolean expressions.
• Digital Logic Concept Map. Concept map for digital logic as covered during the last 8 weeks of class. Created on Wed. 4-23-14 in class.
• Transformers video and Transformers Notes. Transformers, mutual inductance, ideal transformers, turns ratio, voltage and current ratios, and use of transformers in power supplies.
• AC to DC Conversion video and AC to DC Conversion Notes. Characterization of AC voltages and AC to DC conversion using half-wave and full-wave rectifiers.
