文章首次提出了只用一块 CMOS 集成电路就能产生1.5T 帧同步信号的简便电路。该电路的优点是:简单,便宜,高精度以及高可靠性,有实用价值。一、引言这里介绍:仅用一块 CMOS 器件,就能产生1.5T 帧同步信号的原理、方法和电路。帧同步的重要性。在数字式时分多路信息传输系统中所传信息是用一串数码表示的。接收机应在指定的时刻对收到的码元的有、无进行判决,以便复制出代表所传信息的数码。这就需要码元(位)同步。此外,还需帧同步。时分多路(如通信等)系统中,不管是数字的还是模拟的,
The article first proposed a simple CMOS integrated circuit can generate 1.5T frame synchronization signal simple circuit. The circuit has the advantages of: simple, cheap, high precision and high reliability, practical value. I. Introduction Introduction here: Only a CMOS device, can produce 1.5T frame synchronization signal principle, methods and circuits. The importance of frame synchronization. The information transmitted in the digital time-division multiplexed information transmission system is represented by a series of digits. The receiver shall, at the designated moment, evaluate the presence or absence of received symbols in order to reproduce the digital representation of the message transmitted. This requires symbol (bit) synchronization. In addition, the need for frame synchronization. Time-division multiplexing (such as communications, etc.) system, whether digital or analog,
