GIF — The Elusive Phase Lock

phase_lock_2

Not actually elusive*, as this happens on a regular basis inside your phone, computer and nearly everything else with a clock or carrier, but I thought it would look cool as a GIF, so I made one.

This is a PLL achieving lock in an 8x multiplier circuit after a frequency shift. I could watch this all day.

*- can actually be elusive if you’re not familiar with loop filters.
