是一款 6U 单插槽 VMEbus 模块，可为我们的嵌入式 VMEbus 处理器系列提供硬盘和软盘存储选项。该模块可以单独配置一个驱动器，也可以同时配置两个驱动器。闪存驱动器可作为选件提供。VME-7452 是无源 VMEbus 板，仅连接到 P2 用户定义的引脚、电源和接地。

其振幅仅取有限值的信号称为数字信号。数字信号是离散的，它们只包含不同的值。数字信号以位的形式携带二进制数据，即0或1，它在一段时间内只能包含一个值。数字信号表示为方波或时钟信号。

zui小值为0伏，而值为5伏。与模拟信号相比，数字信号较少受到噪声的影响。数字数据在模拟信道中的传输是通过一种称为调制的过程来完成的。振幅调制是使用单频载波信号将数字数据转换为模拟信号的过程。类似地，频移键控使用恒定振幅载波信号和两个频率来区分1和0。

It is a 6U single-slot VMEbus module that provides hard and floppy disk storage options for our family of embedded VMEbus processors. The module can be configured with a single drive or two drives at the same time. Flash drives are available as an option. The VME-7452 is a passive VMEbus board, connected only to P2 user-defined pins, power supply, and ground.

A signal whose amplitude takes only a finite value is called a digital signal. Digital signals are discrete, they only contain different values. Digital signals carry binary data in the form of bits, i.e., 0 or 1, which can only contain one value at a time. The digital signal is represented as a square wave or clock signal.

The minimum value is 0 volts, while the value is 5 volts. Digital signals are less affected by noise than analog signals. The transmission of digital data over analog channels is done through a process called modulation. Amplitude modulation is the process of converting digital data into analog signals using a single frequency carrier signal. Similarly, frequency shift keying uses a constant amplitude carrier signal and two frequencies to distinguish between 1 and 0.
