    Thanks for the video, it clears up some of my confusion when it comes to tank circuits. I have always maintained that if you can learn one new thing every day, it will keep your mind active, and prevent age related deterioration. You sir, are keeping my mind young and active. Combine this with our desire to see new and wonderful things by traveling these United States of America, and I can stay young for ever!

    I built one simple Pearson-Anson oscillator. It creates a saw tooth signal with a glow lamp and was used in analog sound synthesizers.
    Glow lamps have also been used in noise generators.

    I recently learned that you can make a square and triangle wave oscillator using a single op amp. It is simply an RC circuit in a comparator (I think that is what the configuration is). The capacitor determines the frequency range. Higher = Lower frequency range. I used a 10uF capacitor and my range was 1-200Hz.

      Apply a known high frequency square wave with a known voltage and measure current flowing through it, then you can calculate the freq. by using the coil reactance formula backward.

    • @kameelamareen

      You can measure it using a Maxwell Bridge, its a null type AC Bridge that measures the inductance and also the resistance of an Inductor (quality)

    Great video. I don't know anything about this kind of thing. But for whatever reason I woke up and wanted to know exactly how a radio works. I looked at page after page, video after video that just told me that a carrier wave has a modulated wave blah blah but no one mentioned anything about how the carrier wave was made. After a few hours I was yelling at the screen WHAT MADE THE CARRIER WAVE, GOD? MAGIC? Anyway, thanks, this video explained a lot about how waves/frequencies/etc are created in the first place. :)

  • @rockndancenroll
    @rockndancenroll 7 лет назад +3

    Thank you for this video, I used the topology at 4:39 for the colpitts and it works perfectly.
    However, I cannot really grasp how the LC tank is formed (inductor is not in parallel with the two capacitors), and how the output of the LC tank is connected to the input of the amp ( I don't see a feedback path going to the base of the bjt).
    Could someone please briefly answer me those two questions? Thanks

    • @kaustubhmurumkar2670
      @kaustubhmurumkar2670 4 года назад +1

      1) It is an LC series resonance circuit
      2) The capacitor voltage divider is connected to emitter resistance, it acts as a negative feedback.

    1:25 I don't really understand how the capacitors get charged alternatingly. Unless I'm overlooking something, the circuit is perfectly symmetric, right? So by my logic, C1 and C2 should get charged at the same time and should then activate the transistors at the same time. Also, how does C1 discharge exactly when transistor Q2 is conducting but not Q1? Through the base of Q2? If there's still someone who reads these comments, please explain! Thanks!
