deCoding

解碼是一種用特定方法，把數碼還原成它所代表的內容或將電脈沖信號、光信號、無線電波等轉換成它所代表的信息、數據等的過程。解碼是受傳者將接受到的符號或代碼還原為信息的過程，與編碼過程相對應。[1]

基于單片機系統的(24,16)循環碼編碼、譯碼方案

　　在理論分析循環碼編碼和譯碼基本原理的基礎上，提出了基于單片機系統的(24，16)循環碼軟件實現編碼、譯碼的方案。仿真結果表明(24，16)循環碼能有效地克服來自通訊信道的干擾，保證數據通信的可靠及系統的穩定，使誤碼率大幅度降低。本論文對(24，16)循環碼的研究結果表明，可以有效地降低錯誤概率和提高系統的吞吐量，實現糾錯僅需要在接收端增加有限的存儲空間和計算復雜度，具有一定的實用價值。　　Abstract: 　　Based on analyzing the theory of encoding and deCoding of cyclic code， this paper showed the schemes of encoding and deCoding of(24，16)cyclic code by the software and based on microcontroller. Simulation results show that using (24，16) cyclic codes can effectively overcome the interference from communication channel， ensure the reliability and stability of data communication systems， and reduce the bit error rate greatly. The results of this paper show that by using the (24，16) cyclic code， the error rate can be reduced and the system throughput can be improved. Meanwhile， the system only needs to enlarge limited storage space and computation the complexity at the receiving end to realize error correction. Thus the (24，16) cyclic code has a practical value.

基于MT8880的一鍵撥號電話系統設計

　　針對煤礦井下調度及緊急救援系統的需求，以DTMF編解碼模塊為核心，設計了具有自動撥號功能的新型電話系統。該系統利用MT8880對DTMF信號的編解碼功能實現一鍵撥號和遠程設置，通過檢測振鈴和忙音信號，完成自動摘機和掛機過程，配合AGC等外圍電路達到話音清晰流暢的效果。　　Abstract: 　　To meet the demand for mine scheduling and emergency rescue system， with using DTMF signal codec as the core， a new telephone system was designed with automatic dialing function. In the system， the DTMF signal encoding and deCoding function of MT8880 was used to achieve one-touch dialing and remote setting. The circuit detects the ringing and busy signal， and then completes automatic off-hook and hangup. With AGC(Automatic Gain Control) and other peripheral circuits， the voice was regulated to a clear and smooth effect.

DTMF deCoding with a PIC16xxx

This application note describes how to decode standard DTMF tones using the minimum number of external discrete components and a PIC. The two examples use a PIC which has an 8 bit timer and either a comparator or an ADC, although it can be modified for use on a PIC which has only digital I/O. The Appendices have example code for the 16C662 (with comparator) and 16F877 (using the ADC). As the majority of the Digital Signal Processing is done in software, little is required in the way of external signal conditioning. Software techniques are used to model the individual elements of a DTMF Decoder IC.

水位監測報警系統原理

摘要：本水位監測報警器使用5V低壓直流電源（也可以用3節5號電池代替）就可以對5~15厘米的水位進行監測，用LED顯示和數碼管顯示水位，并可以對不再此范圍內的水位發出報警。主要采用CD4066、74LS86、74LS32、CD4511芯片，再加上數碼管、蜂鳴器、發光二極管、電阻這些器件組成一個簡單而靈敏的監測報警電路，操作簡單，接通電源即可工作。因為大部分電路采用數字電路，所以本水位監測報警器還具有耗能低、準確性高的特點。關鍵字：譯碼電路報警電路監測電路 Abstract: The water level alarm monitoring the use of 5 V low-voltage DC power (can also use three batteries replaced on the 5th) will be able to 5 to 15 centimeters of water level monitoring, with LED display and digital display of water level, and this can no longer Within the scope of a water level alarm.
