This project presents a complete end-to-end implementation of Quadrature Phase Shift Keying (QPSK) — a digital modulation technique used in real-world communication systems such as satellite, Wi-Fi, ...

This project simulates the 3D attitude control of a quadcopter using PID controllers in MATLAB. The simulation numerically integrates the quadcopter’s nonlinear equations of motion using the ODE45 ...

Abstract: The increasing demand for high-speed optical interconnects requires the integration of photonics and electronics, with electro-optic (EO) co-simulation being crucial. However, fragmented ...

Abstract: DC analysis is the foundation for nonlinear electronic circuit simulation. Pseudo transient analysis (PTA) methods have gained great success among various continuation algorithms. However, ...

In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...
