Questions tagged [oscillation]

Oscillation refers to the repetitive variation of electrical signals.

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. In the context of Electrical Engineering, oscillation refers to the repetitive variation of electrical signals.

How does this old oscillating light board work?

I know EE.SE loves a good treasure hunt, so here's one to noodle on. This device was made in the 1950s or 1960s by a Bell Labs EE. He designed it as a toy to amuse his young son. Said child, now turning 70, has asked a family member (me) how it…

Damped Oscillations Start with a Delay

I feel like a total newb here, because I've built resonant tank circuits plenty of times before, but somehow I'm stumped on this one. I've run into a bizarre problem I can't figure out. See scope shot: The top channel is my signal to the gate of a…

Dave Jones's uCurrent - oscillations

uCurrent is a tool for measuring small (micro) currents by Dave Jones (EEVblog). He published source files: https://www.eevblog.com/projects/ucurrent/ I took his schematic and recreated in KiCad (no changes in schematic). Then created my own PCB…

Quartz oscillator using a large irregular (natural) piece of quartz crystal for maximum Q?

Background Based on helpful comments and links here and also from my question on the physics stackexchange, I have learned that the quartz crystals are nature's transducers of energy, allowing electrical energy to be converted into mechanical energy…

How could I get something to oscillate at 2295 Hz?

I am curious on making things oscillate. I would love to do this with one chip, but if there was a chip that oscillated at 2295 Hz, I have no idea where it is. So the question is, how could I use an LC or RLC circuit to oscillate ate 2295 Hz? I have…
