抖晃概述 信息是如何存储到光盘上并从光盘上读取的? CD和DVD光盘分别载有它们各自的信息,是通过 反射光从高电平到较低电平再回到高电平的量的变化实 现的。这种情况造成了光的强度向上升或下降两个方向 的跃变。数字信息存在于所选择的跃变之间的长度,这 种跃变还用来再生带有时钟周期T的信息位时钟。通过 使用位时钟,播放机就能识别被称为符号的3T,4T直 到11T和14T的分立的长度,从而从光盘中读取数据。这
Jitter Overview How the information is stored on a disc and read from it? CDs and DVDs contain their own respective information, which is reflected by the reflected light from high level to low level and back to high level The amount of change achieved. This situation caused the light intensity to rise or fall in two directions of the jump. The amount of digital information that exists between the selected transitions is also used to regenerate the information bit clock with a clock period of T. By using the bit clock, the player can recognize the discrete lengths of 3T, 4T, referred to as symbols, up to 11T and 14T, to read data from the disc. This
