Feedback & Oscillator Circuits
An oscillator is an electronic device for generating AC signal voltage. Oscillators generate sinusoidal or non-sinusoidal waveforms from very low frequency to very high frequencies. In this course, you'll learn about Feedbacks in Opamps and oscillators. This is the course usually taught in Electronics and Communication engineering.
