Happy holidays to all. If you have some time and are interested I am still looking for specialized help to give my book http://www.wiley.com/WileyCDA/WileyTitle/productCd-0471520195.html a new life as I drifted in to Meta Material Based Structure based Signals Sources. The key missing parts are an in depth treatment of Arbitrary Waveform Generation (in base band) , precision I-Q modulation (modulator/demodulator) and all resulting in a Vector Signal Generation architecture . Modern Synthesizer based Signal Sources use these technologies . Who has the time, will put up the sleeves and will work with me ? Thanks, 73 de Ulrich, N1UL _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
