(2)MP3/MP4方框图的种类方框图种类较多,具体说明如下:①整机电路方框图从整机电路方框图中可以了解到整机电路组成和各部分单元电路之间的相互关系,通过图中的箭头还可以了解到信号的传输途径等。图1所示就是炬力2089方案MP3的整机电路方框图。②系统电路方框图一个整机电路是由许多系统电路构成的,系统电路方框图用来表示该系统电路组成情况,它是整机电
(2) Types of MP3 / MP4 Block Diagram There are many types of block diagrams, and the details are as follows: ① Complete Circuit Diagram The whole circuit diagram and the relationship between the unit circuits of the whole circuit can be seen from the block diagram of the whole circuit. The arrow also can understand the signal transmission route. Figure 1 shows the circuit diagram of the full circuit of Actions 2089 Program MP3. ② system circuit block diagram A whole circuit is composed of many system circuits, the system circuit diagram is used to indicate the system circuit components, it is the whole machine
