序列检测器可用来检测一组或多组由二进制码组成的脉冲序列信号，这在数字通信领域有广泛的应用。当检测器连续收到一组串行二进制码后，若这组码与检测器中预制的码相同，输出为A，否则输出为B。序列检测I/O口的设计如下：设Din是串行数据输入端，clk是工作时钟，clr是复位信号，D是8位待检测预置数，QQ是检测结果输出端。-Sequence detector can be used to detect one or more sets consisting of binary code from the pulse sequence signal, which is a broad field of digital communication applications. When the detector continuously received after a group of serial binary code, if this group of pre-code and the code detector in the same output as A, otherwise the output B. Sequence detection I/O port design are as follows: Let Din is the serial data input, clk is work the clock, clr is a reset signal, D is the 8-bit preset number to be detected, QQ is the test results output.
