Dan Baker's Personal Home Page at Hevanet

Hello, my name is Dan Baker and welcome to my simple homepage. I wrote this page directly in HTML using Notepad so I appologize for it's plain-vanilla appearance. I am an electrical engineer with a background in RF, digital and analog signal processing. I am a principal engineer for Tektronix's Video Product Design group and have been designing video waveform monitoring equipment in this same group for over 30 years. I have a MSEE from Oregon State University, a BSEE from University of Portland and over 20 US and foreign patents.

The chart below can be used to measure the "gamma" or power-law exponent of the display you are using.

View this chart at a distance and find the matching squares. The gamma values are listed on the bottom row. Note that the Brightness (or Blacklevel) of your monitor affects gamma and should be adjusted such that the measured gamma value matches within 0.2 for all rows.
