Numerically Controlled Oscillator from Microchip

The Numerically Controlled Oscillator (NCO) module is a timer that uses the overflow from the addition of an increment value to divide a frequency. The advantage of the addition method over simple counter driven timer or a PWM is that the resolution of division does not vary with the divider value resulting in true linear frequency control. The NCO is most useful for applications that require linear frequency control, high frequency accuracy and fine resolution at a fixed duty cycle, e.g., Lighting and Ballast Control, Tone Generators and Resonant Power Supplies.

  • In the future, will Autodesk products all be used online?

    TechCrunch just posted this video, where Andrew Keen interviews Autodesk CEO Carl Bass. The interview is about 12 minutes long. About 2 minutes in, Bass makes possibly the most interesting comment in the interview: “I’d say two to three years from now, every one of our products will be used online. The only way to [...]

  • Autodesk provides real-time DFM for plastic part design

    There’s a lot of benefit to be had by doing manufacturability analysis (DFM, Design for Manufacturing) early in the design process, rather than waiting until later, when design changes are far more expensive. A couple of years ago, Autodesk Labs previewed a product, Project Krypton, which ran inside of 3D CAD programs (including Autodesk Inventor, DS SolidWorks, and PTC [...]
