I just found your 11/09/2005 article on Ghz microwave eavesdropping.
I have a question: what frequency ranges would this work for?
I was thinking that since cell phones are FM and not AM, a 3G cell phone at ~2.1Ghz is on the low end of the microwave range. Could someone use reflections of an individual's cell phone traffic to listen in? (Not that this would be easier than grabbing the cell phone traffic itself...)
What about Wi-fi? WiMax? Once WiMAX goes up, everyone will be basking in Ghz signals.
Blog Doing Math in FPGAs Tom Burke 15 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
Finding out the perceived frequency response of your combined headphone/ear 'system' and compensating for it using parametric equalization can offer some eye-opening benefits. But finding an EQ solution isn't always easy.
