Agenda Recap complex numbers Relationship Laplace, frequency (Fourier) domain Relationship time, s and frequency domains decibel notation (dB) RC circuit as a Low-Pass and High-Pass filter Bode plots Combination filters

Complex number in complex plane Argument of s Absolute value of s (aka Modulus or Magnitude)

Operations on complex numbers cont. Multiplication/division using Euler’s notation

Operations on complex numbers cont. Complex conjugate Multiplying a complex number by its conjugate gives a real number

Relation Laplace and Fourier Transform s-domain (Laplace Domain) Time domain -domain (Frequency Domain) Time domain Transient response (step, impulse) Frequency response (filters)

Relation time, s and frequency domain i Time domain Laplace (s)-domain -domain

Concept of impedance (Capacitor)

Concept of impedance (Inductor (coil))
