Teaching analog electronics circuits this quarter to second year undergraduates and it has been quite a thrill covering topics from frequency response, filters to oscillators. Bringing to students an intuitive understanding of how circuits function, why they behave the way they do, their optimal operation points, criteria for oscillation and their differences between passives and actives has been fun, challenging and rewarding experience.
As an advanced topic on oscillators, I covered a variety of oscillators from linear to nonlinear. I brought a few metronomes to experiment live abstract concepts such as “oscillator coupling in-phase/out-of-phase” synchronisation and “subharmonic injection locking”. It was a fun experience for us all and some of them already want to couple many more oscillators 🙂 They are the future circuit designers!
