FSK-DTMF
- AVR mega16单片机上实现FSK和DTMF解码的程序，信号由AD 7.2K采样，是可用的，但具体使用时需要根据硬件条件对参数略作调整。-mega16 achieve FSK and DTMF decoder procedures, AD 7.2K signal from the sample is available, but the specific use of the hardware required under the right conditions parameters sl
MT8870DataSheet
- The MT8870D/MT8870D-1 is a complete DTMF receiver integrating both the bandsplit filter and digital decoder functions. The filter section uses switched capacitor techniques for high and low group filters the decoder uses digital counting te
DTMF
- 通过单片机（例如：HT95系列、EMC78系列、MCS51系列等）和外围电路的设计应用三级管的3个特性区，结合程序来实现来电显示的解码。此方法能提供比较高的稳定性和可靠性。在设计应用中，免去了因采用FSK或DTMF专有解码芯片的高额成本。-Through the SCM (eg: HT95 series, EMC78 series, MCS51 series, etc.) and external circuit design and application of the three chara
