32.768kHz Crystal Oscillator Waveform with and without External Power

This video explores the waveforms of a 32.768 kHz crystal oscillator.
The 32.768 kHz crystal oscillator is commonly used in various electronic devices for real-time clock (RTC) applications.
The RTC modules in this microcontroller also use a 32.768 kHz crystal to keep track of time.
In this experiment, the two 10X probes are connected to the two pins of the crystal.

Nice, cool ociloscope 😊

its so funny to me how computers use crystals and vibrations to track time, so a rock that a bunch of really smart people engraved could communicate with us, in an electricity(aka lightning) based language that you need to learn for years, and we use said rocks to move information a stupidly large distance almost instantly, and calculate stuff that would take generations in a fraction of the time. it sounds like something from a medieval magic fantasy or a conspiracy theory

why 32.768khz instead of just 32,768hz? Also, what AI voice is this?

[@tpg3942]

"32.768 kHz" is a common way to represent a frequency in kilohertz (kHz)；TTS technology has a long history predating modern AI advancements. Companies like Microsoft and IBM have been among the pioneers in providing TTS services.

@@tpg3942 So it's industry standard to use "khz" with enough significant figures that there's no benefit over "hz" ?
