Sometimes it seems as though digital designers get all of the attention. In all of the excitement surrounding "gigaFLOPS," "22 nm," and such, there's still one crumb of comfort for we non-digital ...
With modern microcontrollers, the process of interfacing with the analogue world is easy. Simply enable the on-board DAC or ADC, and talk to the world. If you’ve ever done this with a slightly older ...
The R-2R ladder, a well known resistor topology, is often used to implement a current or voltage 6-dB step attenuator. By appropriately scaling the resistor values ...
