Then power consumed by the dash camera is: P =VI =(4.2)(0.8)= 3.36 W
Also, power generated by the voltage source is: (5)(0.8)=4

5. Capacitors and Inductors
The analysis techniques that were introduced in the previous chapters only involved resistors, DC
voltage and current sources. These components are all static - They do not allow for any dynamic
change in the voltage or current

3. Analysis of Resistive Circuits
Chapter two covered the definitions of various parameters relating to electronics and their relationships amongst each other. However, it did not cover the circuit itself and how they are analysed.
This chapter introduces

11. Sensors Part 2
As mentioned at the beginning of the previous chapter, this chapter continues the discussion about
sensors by focusing on the piezoelectric sensors and the temperature sensor.

8. Electronic Filters
Chapter 7 introduced the Laplace domain and its application for circuit analysis. This chapter shall
then apply the material learned from Chapter 7 to a very useful tool for signal processing - The
electronic filter. As aforementione

2. Physical Concepts for Circuit Theory
The foundation of electronics begins in the study of DC circuits and the associated common used
components. To begin this block of study, the fundamental concepts for circuit theory shall first
be explored. This cha

4. DC Circuit Analysis Methods
Chapter covered the basic concepts that can be used to analyse resistive circuits with 1 power source
or when multiple power sources are involved, they can be simplified to a single equivalent power
source. When multiple pow

Overall, this course has presented some fundamental electronic concepts and how they are applied
in the field of signal processing and sensors. The first part introduced some basic electronic ideas
such as KCL, KVL, DC circuit analysis techniq

10. Sensors Part 1
The content in the previous part has focused upon processing the raw signals from sensors so that
they can be directly interrupted by the end user system. This part now focuses on the design of
sensors themselves. As of today, there are

7. Circuit Analysis in Laplace Domain
By the law of Fourier transform, any arbitrary signal can be represented as a infinite sum of sine
and cosine waves of all frequencies. Subsequently, the principles of signal processing are all based
on the frequency

in the forms of voltages and currents. In the electrical circuits, these signals are called analog
signals. However, in computers
