ASK, PSK, FSK Random Signal Generation Program with Algorithm Implementation

This program generates ASK, PSK, and FSK random signals through systematic implementation steps. The code structure is straightforward yet practical for digital communication applications. First, the program generates ASK (Amplitude Shift Keying) random signals. ASK is a modulation technique that alters signal amplitude based on binary data bit values. The implementation typically involves: - Generating a carrier wave using sine functions - Mapping binary '1' to high amplitude and '0' to low amplitude - Using element-wise multiplication between binary data and carrier signal Key function: Amplitude modulation through conditional amplitude assignment based on input bit sequence. Second, the program creates PSK (Phase Shift Keying) random signals. PSK modulates signal phase according to binary data values. Implementation features include: - Phase shifting of carrier signal by 0° for binary '0' and 180° for binary '1' - Using cosine functions with phase adjustment parameters - Implementing phase transitions through angular displacement in trigonometric functions Algorithm explanation: Binary data directly controls phase offset in the carrier wave equation. Third, the program produces FSK (Frequency Shift Keying) random signals. FSK changes signal frequency based on binary data bits. Code implementation involves: - Assigning different frequency values to binary states (e.g., f1 for '0', f2 for '1') - Generating continuous waveform with frequency switching - Using time-dependent frequency modulation in the sine function arguments Key implementation: Frequency selection through conditional statements controlling the angular frequency parameter. The program employs clear modulation algorithms and practical coding approaches, making it suitable for various communication requirements. Each modulation technique maintains separate function modules with configurable parameters for carrier frequency, amplitude levels, and phase shifts. The code structure allows easy integration with digital communication systems and signal processing applications.
