PHY2203 ELECTRONICS

This course introduces the student to the general concepts of electronics; analog and digital electronics. Analog electronics covers circuit theory, electronic devices, introduction to 3-phase power supply and differential amplifiers. The digital electronics covers logic gates, combinational and sequential logic, analog-to-digital converters and digital-to-analog converters.

Course Objectives
By the end of this course, students should be able to

• Use the superposition principle and Thevenin’s theorem
• Draw the I-V characteristic of a junction diode and explain its common uses
• Calculate the voltage gain of a transistor amplifier
• Write down the output voltage of the inverting amp, non-inverting amp and the summing amp, and derive the output of an integrator circuit and a differentiator circuit using an op-amp.
• Explain the difference between an analog and a digital signal
• Draw the circuit symbols of common logic gates and their truth tables
• Explain the need for analog-to-digital and digital-to-analog converters, and describe some common methods used in these converters.
• Perform experiments to link theory to practical concepts
