Скачать или смотреть #26: The Wien bridge oscillator

This video describes a simple Wien bridge oscillator circuit based on a 741c operational amplifier. We walk through the analysis of circuit, compute expected circuit properties based on component values, and demonstrate a breadboard version of the circuit. Additional resources can be found at several websites, including https://www.maximintegrated.com/en/ap..., http://www.ti.com/lit/an/sloa060/sloa..., https://leachlegacy.ece.gatech.edu/ec..., and (of course) a very nice chapter in The Art of Electronics, 3rd edition (chapter 7).
