Nikola Tesla slideshow: Images and articles from Tesla’s writings. This slideshow contains a sampling of images and excerpts from John Ratzlaff’s collection, which are all obtainable on the Internet. There are also several links to other awesome sites with info on Tesla.

Giga Sample and Direct-RF Sampling ADCs Overview. This video from TI demonstrates TI’s direct RF-sampling ADC IMD3 performance at 700 MHz and 2.7 GHz, allowing the elimination of one or more down-conversion stages. Features: sample rates up to 3.6 GSPS, dynamic performance up to 2.7 GHz inputs, largest high-res Nyquist zone at 1.8 GHz, and pin compatibility with TI’s 10- & 12-bit ADC families.

The basics of FPGA mathematics. For better performance, you can implement some digital signal processing (DSP) algorithms in an FPGA. This article takes a look at the rules and techniques that you can use to develop mathematical functions within an FPGA or other programmable device.
