    Every University Teacher must watch this before teaching to students. Perfect, clear and neat way to explain. I request your team to continue posting such videos. Thank you so much.

      My points exactly. As someone recently called to teach simplified communications in radio, these videos are an excellent source of refreshment of essential principles. I love the concise and pitch (for my level of interest anyway) of these videos and will take a leaf from the presentation style of these presentations.

    I recently purchased a NanoVNA to tune my HF amateur radio antennas minimising the needing for a matching transformer. However, I was sticking to the VSWR display because the Smith chart looked complex. Thanks to this video I have found out so much more from reading Smith chart graphing now that I understand them! Thanks for making this understandable and clear.

    This was a great refresher after barely using it for a few years. Also, I don't remember my profs teaching that it was a transformation of the cartesian representation, that definitely makes this easier to understand.

    I’m so impressed by how effective your short videos on VSWR and S Parameters are. I’m a lecturer who hasn’t worked in the field for many years but does occasionally dabble as a hobbyist. Recently I have been called upon to teach fundamental radio communications and it’s very refreshing to see these videos. Thank you.

    Excellent. Just excellent... being a maths "dumbo" I've always struggled with the Smith Chart. Being a licensed radio amateur a proper understanding of the chart, it's functions, AND HOW THEY CAN BENEFIT ME by properly understanding them escaped me year on year,. NO MORE. Paul, Thank You ! this presentation should be part of every single radio amateurs course !
    Am very very grateful to you for this more than excellent video. Your companies instruments for us radio amateurs are the stuff dreams are made off. Sadly... lottery tickets to win them are far and few between... but,... we live in hope!
    Thank you again Paul.

    That was really well done. It was the perfect presentation style (at least for me). And there was little to no subtle marketing of your company's brand; you simply presented the base concepts along with some historical background of who the Smith in "Smith Chart" was. I understand this so much better now. Thank you.

    Vague and distant memories of my father and some members of his ham radio club, designing their own antenna's. There was one of these charts laying on the bench. My 8 year old self got introduced to "imaginary numbers" it would be some 15 years later that this made any sense.

    • @pauldenisowski
      @pauldenisowski Месяц назад

      I think the second biggest mistake in the history of mathematics was using the word "imaginary" (instead of "complex") to describe these kinds of numbers. (The biggest mistake was Roman numerals😂)

    Useful because my Extra ticket expired during a crazy time of life, and I will be retaking it, building a station, and doing SOTA POTA outings.
    Practical,
    because 4.2" TFT display, 50Khz-1Ghz VNA's can these days be had for $90-$100 delivered.

    Great presentation. In the example at 8:47, when you normalize the complex impedance, why does only the sign on the resistive component change? If I factor out -1, shouldn't we get -100 + j75 = -(100-j75)? Then -Z/50 = 2 -j1.5?
