Create an input binary source, apply OOK, FSK, and PSK modulation techniques, and visualize modulated waveforms and frequency spectra

Detailed Documentation

Before implementing OOK (On-Off Keying), FSK (Frequency Shift Keying), and PSK (Phase Shift Keying) modulation techniques, it is essential to generate an input binary source. This binary source can be either random or patterned, generated programmatically using algorithms like random number generators or predefined sequences. Common implementation approaches include using MATLAB's randi() function for random bit generation or creating structured patterns with repeating sequences. After modulation, waveform and frequency spectrum plots should be generated for comprehensive analysis and interpretation. These visualizations help characterize modulation effects and signal transformations during transmission, with typical implementations involving Fourier transforms for spectral analysis and time-domain plotting functions for waveform display.
