Publisher's Synopsis
Would you believe that today's most sophisticated wireless communications systems are based on the geometry and trigonometry taught in high school?
It's true! This book applies basic geometry and trigonometry to complex numbers to establish a proper mathematical foundation for a successful DSP career. The basics of complex numbers and complex sinusoids are shown with easy to understand mathematics and color figures:- Understanding Euler's formula
- Addition, multiplication and division of complex numbers
- Why are sinusoids used in DSP and RF?
- Instantaneous phase and frequency
- Negative frequency
- Derivations for sine and cosine as complex exponentials
- How sine and cosine are derivatives of one another
- Product to sum trigonometric Identities
