The Magic of Clocks: A Battle Between Synchronous and Asynchronous Communication, Like a Conductor Leading a Symphony and a Romantic Date Based on Mutual Understanding Understanding them is to grasp the cornerstone of modern communication. Have you ever wondered: “Synchronous communication requires a clock, while asynchronous communication requires matching baud rates. Wait? If the baud … Read more
In the world of electronics, there is an inconspicuous little component that almost determines whether a microcontroller can function properly, and that is the crystal oscillator (晶振). It acts like the “heart” of the microcontroller; without it, the microcontroller would be “lost”. So, why must microcontrollers use crystal oscillators? Today, we will uncover its secrets. … Read more
1. What is a Clock Signal The clock signal (Clock Signal) is the foundation of sequential logic, used to determine when the states in logic units are updated. It is a signal with a fixed period that is independent of operation. The clock signal has a fixed clock frequency, which is the reciprocal of the … Read more
