Wow! An amazing series (ECE Topics) that has helped me to better understand many concepts. With great examples and visuals these are amazing quality productions. Thank you and looking forward to wherever direction you go.
Very glad it helped. I owe some of the production to Pinnacle Studio and the ability to cut out pauses and "ah"s and such 🙂 Not sure where to go next. Thanks for leaving this encouragement.
I want to say thanks for this videos, they are very usefull in the sense that it bring all this stuff to groud and seem more aplicable. What program or how do you make this slides? Thanks again.
You are very welcome. I appreciate your feedback and knowing that the presentations are helpful. I use Powerpoint to make the slides. I've also found that using the Windows "Snipping Tool" helps in bringing in photos/etc with simple cntl-C and cntl-V keyboard shortcuts. Plus I use some image editing programs I have to modify 'gamma', etc if the videos are not light enough for example. A lot of the circuit diagrams are hand-drawn in Powerpoint using their "Shapes" menu - and I confess I have mixed feelings about the PPT user interface there. But over time I've begun to appreciate it (including the equation editor). For the assembling the videos themselves, it's a collection of things. A couple Canon cameras for taking main video shots and photos. And then Pinnacle Studio for assembling/editing. I also use MultCam Capture for adding the voiceovers. I don't recall where it came from, but It works for marking an area of the computer screen and 'filming' that while using a microphone to overlay sound when going through the PPT slides. I'm sure there are better ways to do that, and most if not all of these things - but this is what I accumulated over the years 🙂
High Frequency is picked up early in the cochlea as you indicate, which is an indicator of why the higher frequencies are diminished due to loud noise exposure/damage. Or so I was told by an audiologist. Those little cilia are destroyed by the loud sound whereas the cilia inside (low freq) the cochlea are further away & better protected.
Good to learn. Thanks for the info! I always use ear plugs when sounds are above 100 to 120 dB. Went to a concert once in my teens where my ears "rang" for about 30 minutes after it let out. I figured that was bad - so I never repeated that mistake. Fortunately, I still have pretty good hearing 50 years later. Just the usual loss above about 10 or 12 kHz.
Yep. Fun stuff. Along with Laplace (which is the continuous time version). I've been hesitant to tackle that math in too much depth so far. BUT - I did recently find this excellent video on the "Curio Res" channel. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HJ-C4Incgpw.html She has put together an amazing video for those interested in Arduino _implementations_ of digital lowpass filters. Some Z domain transfer functions and associated difference equations show up a little after 3 minutes 30 seconds into it. I like her presentation style, and she shows coding too :-)
*WHERE IS YOU EMAIL?*---I need to contact you but couldn't find your email, neither on RU-vid nor on your website. I have a few questions about building antennas. Please tell your email address.
Sorry - I don't publish that. But I saw your question on another video - hopefully my answer was helpful. Feel free to ask questions in the public video comments. That way others with similar questions/ideas can benefit and/or help out as well.
