Active video filter

Originally, video filters were passive LC circuits surrounded by amplifiers. Smaller, more efficient designs can currently be achieved by combining the amplifier with an RC filter. Sensitivity analysis and predistortion methods developed in the 1960s have, moreover, overcome the poor performance that gave early video filters a bad reputation.

Low voltage brushed motor system

This brushed motor system uses an MSP430 microcontroller, a DRV8837 brushed DC motor driver, and a 12V brushed motor. This system is suitable for applications requiring speeds up to 10,300 RPM under no load conditions. The system measures 19 x 33 mm without motor, making it ideal for applications requiring a small footprint. The motor power supply voltage supports 1.8V to 11V, and the maximum current is 1.8A. There are various configuration options for easily controlling the rotation of the motor, changing the direction of rotation, and placing the system into a low-power state to reduce energy consumption when not in use. The motor drive platform incorporates protection against short circuit, breakdown, undervoltage and overheating.
