Generating Fundamental Signals with MATLAB

The following programs are implemented in MATLAB to generate fundamental signals such as sine waves, square waves, and impulse sequences, which serve as building blocks for signal processing systems. These programs incorporate essential waveform generation functions including sin() for sinusoidal signals, square() for rectangular waveforms, and dirac delta implementations for impulse responses. The generated signals can be utilized for signal processing and analysis to understand signal characteristics and behaviors through time-domain visualization and frequency spectrum examination. By modifying and extending these programs, users can implement more complex signal processing tasks such as digital filtering using filter design functions (e.g., butter, cheby1), spectral analysis through FFT algorithms (fft(), pwelch()), and signal modulation techniques. These programs provide an excellent starting point for understanding signal processing principles and applications, demonstrating core MATLAB functions like plot() for visualization and sound() for audio output. Furthermore, by learning the MATLAB programming language, users can explore and develop custom signal processing algorithms and applications, utilizing built-in toolboxes like Signal Processing Toolbox and DSP System Toolbox. Overall, these programs serve as valuable learning resources for beginners, establishing a solid foundation for further expansion and application in the signal processing field through practical code examples and modular program structure.
