Hello everyone, in this lesson we will talk about the role of crystal oscillators in electric motors

2

00:00:09,766 --> 00:00:17,700

We said before that the crystal oscillator can output a fixed and stable clock frequency

3

00:00:18,900 --> 00:00:22,700

So what is this clock frequency for?

4

00:00:23,700 --> 00:00:30,200

The clock frequency is to allow each chip to work in unison

5

00:00:33,066 --> 00:00:37,300

For example, when we are playing a two-person three-legged game,

6

00:00:37,733 --> 00:00:44,766

we will shout the slogan "one, two, one, two" so that two people can move forward in unison

7

00:00:45,566 --> 00:00:51,900

If there is no slogan, then there is a high probability that two people will wrestle

8

00:00:52,566 --> 00:01:00,766

Such a slogan is also needed in the circuit to make each chip work in unison

9

00:01:01,500 --> 00:01:07,000

This slogan is the clock frequency from the crystal oscillator
