Best FPGA Development Boards for Learning and Prototyping
Field-Programmable Gate Arrays (FPGAs) might sound intimidating at first, but they’re actually one of the most exciting ways to learn digital design. Unlike microcontrollers (like Arduino or STM32) that run instructions on fixed hardware, FPGAs let you design your own hardware. That means you can create custom processors, signal processors, robotics controllers, or even video […]
Difference Between Synchronous and Asynchronous Data Transmission
Data transmission is the fundamental process of transferring digital or analog data between two devices. It plays a vital role in telecommunications, networking, computer architecture, and embedded systems. Two primary methods of data transmission are Synchronous and Asynchronous Transmission. Understanding their differences, working principles, and applications is crucial for designing efficient communication systems. Table of […]
