High Precision Digital Signal Source Board

Built around two ATmega16 microcontrollers, this high-precision digital signal source board is part of a three-board signal generator. The board acts as an interface between a PC/104 controller and an analog output board. The system has seven output channels that can produce sine and user-defined signals with 0.001-Hz resolution. The board also offers eight digital inputs, eight digital outputs, and interfaces with the ADCs on the analog board to the PC/104 controller.
