it's really good to know the history behind these topics as well as the technical aspects. I've seen plans for double sideband QRP construction, is it a mode used at all today? I suppose you can tune SSB into either of the double sidebands?
Hi professor, I have a question, please... For frequency synthesizer/clock recovery scenarios (scenario 1 and scenario 2) where the VCO is noisier than the input, why the phase noise PSD of the VCO is flat (constant) up to the loop bandwidth? I thought it should be 1/f^2 (as open-loop VCO). I thought it should be similar to the phase noise PSD of the input. thanks
Dear Prof. Ali once again thank you very much for sharing your great classes! Also want to say sorry for missing out on your Webinar 1+1=3, but the time of the Webinar was 23:00 in the country I currently am :( Nevertheless looking forward to watch it when it is available at IEEE Solid-State Resource center next week hopefully :) Best Regards!
