Visualizing Signals and Systems: Data Visualization for Communication and Signal Processing using Python and R

"Visualizing Signals and Systems" is a comprehensive, hands-on guide designed to bridge the gap between traditional signal processing concepts and modern data visualization techniques. Using the powerful tools of Python (Matplotlib, Seaborn) and R (ggplot2), this book helps students, educators, and professionals clearly interpret and present complex electronic and communication signals.
Focused on practical application, this guide demonstrates how to transform raw signal data into meaningful, customizable plots. From time-domain and frequency-domain analysis to real-time sensor data visualization, the book covers a wide spectrum of use cases relevant to communication systems, DSP, IoT, and embedded design.
Whether you're working on a lab report, research publication, or final-year project, this book equips you with the skills to visualize and analyze signals effectively using modern coding environments.
Key Topics Covered:
Visualization of analog and digital signals including AM, FM, PWM, BPSK, and QPSK
Plotting impulse, step, and sinusoidal responses of linear time-invariant (LTI) systems
Real-world sensor and IoT data analysis
Frequency-domain plots such as FFTs and spectrograms
Visualization of communication simulation outputs
Comparison of visualization tools in Python and R
Signal interpretation for research, labs, and classroom use
