Low-cost software-defined radio for electrical engineering education
Prototype wireless communication systems can be designed using discrete components, e.g., a low-noise amplifier (LNA), a power amplifier (PA), mixers, filters, frequency synthesizers, an analog-to-digital converter (ADC), a digital-to-analog converter (DAC), etc. Different circuit boards have to be designed, fabricated, assembled, tested, and connected with wires. Consequently, … [Read more...] about Low-cost software-defined radio for electrical engineering education
A buoyancy device design for antisink ships
Ships have many uses in human social life and can be used for various purposes, such as the transportation of people and goods, military affairs, and scientific research. Generally, major ship accidents rarely occur because ships’ design and construction are completed in strict compliance with relevant regulations and international standards (Pan et al., 2020). For … [Read more...] about A buoyancy device design for antisink ships
