调制的解释和 Matlab 代码
沟通不属于其频谱的消息信号的一种方法
内的固定频率范围,或其中一个,否则是不合适的通道,是向
更改一个传染的信号,根据消息信号中的信息。这
改建称为调制,而且它是调制的信号传输。的
接收器然后恢复原始信号通过一个称为解调的过程。
调制是其中一个载波信号根据的资料在改变的过程
消息信号。载波频率,表示 Fc 是载波信号的频率。
采样率,财政司司长,是在消息信号的采样期间的速率
模拟。
载波信号的频率是通常远远大于频率最高
输入的消息信号。奈奎斯特采样定理要求模拟
财政司司长的采样率大于两倍的载波频率总和和
最高频率的调制信号,为了使解调恢复
正确的消息。

可编程中断控制器中断控制器8259A是专门为控制优先级中断而设计开发的芯片。它将中断源优先排队、辨别中断源以及提供中断矢量的电路集于一片中。因此无需附加任何电路,只需对8259A进行编程,就可以管理8级中断,并选择优先模式和中断请求方式,即中断结构可以由用户编程来设定。同时,在不需要增加其他电路的情况下,通过多片8259A的级连,能构成多达64级的矢量中断系统-Programmable Interrupt Controller Interrupt Controller 8259A is designed for control and priority interrupt the core design and development tablets. It will interrupt source priority queuing, identifying the source of disruption and the provision of the circuit interrupt vector set in a Chinese. Thus there is no need for any additional circuit, just right for 8259 A programming, it can manage eight interruption, and to choose the mode and priority interrupt request means that the structure can be interrupted by the user to set programming. At the same time, no additional circuit of the other, through more than 8,259 tablets of class A connected, could constitute up to 64 Vector Interrupt System
