Looking for oscillator learning material

[Danny__]

Hi, I am looking for some plain english teaching of oscillators! I am particularly interested in the use of posotive feedback as I have just studied op-amp's and negative feedback and now want to understand oscillators.

I have plenty of information from an old book but to be honest it is written in gobbledygook!

Some theory

i think this will help you

Hello! Oscillators are devices that generate a repeating waveform, such as a sine wave or square wave. They are used in a variety of electronic applications, including signal generation and frequency control. Positive feedback is a key component in many oscillator circuits, as it helps to sustain the oscillation by amplifying and feeding back a portion of the output signal to the input.

To better understand oscillators and positive feedback, I recommend starting with some basic concepts such as frequency, amplitude, and phase. From there, you can explore how positive feedback works in different types of oscillators, such as the Wien bridge oscillator or the LC tank circuit oscillator.

There are many online resources and tutorials available that explain oscillators and positive feedback in plain English. You can also find some helpful videos on YouTube that visually demonstrate these concepts. I suggest starting with a basic overview and then delving into specific circuits and their functions.

Remember, practice makes perfect, so don't be afraid to experiment and build your own oscillator circuits. This hands-on experience can greatly enhance your understanding and help you apply these concepts in real-life situations. Good luck with your learning journey!
