About me …
I have a Distinguished Engineer position at Loral Space Systems In Palo Alto, CA. I am involved in all sorts of communication system designs. Loral is a world leader in commercial satellites such as DirecTV, Dish, XM, Sirius. Intelsat, Globalstar, Panamsat, to name a few. If you have a satellite dish, more than likely it links to a Loral satellite. My work involves simulation of signal quality through the satellite links. I use SPW by Synopsys for most of my work but also use Matlab. my recent tutorials on DFT, include Matlab code. I have recently started using Simulink and am also trying Octave and Gnuplot.
Before Loral, I worked at Booz, Allen Hamilton, Aerospace Corporation and Northrup, in Los Angeles. I have a MSEE from USC.
I am married, live in Danville, CA, and have two grown children. One works at Apple Computer and the other runs a Publishing company.
I write these tutorials for fun and for love for my field. It is forever challenging and fascinating. I am currently writing a book and hence have not been able to add new tutorials for a while.
