DTMF Decoder for PC

Our DTMF decoder can be powered from a 9V battery or from your parallel printer port. It can detect and display all 16 DTMF digits on your computer screen in real-time. The Window's program can be placed in the minimize mode and still detect tones while you use your computer to do other things like Net surfing!!!! We are now in the process of adding an DTMF decoder which will interface to the sound card gameport.......

DTMF RECEIVER

Today, most telephone equipment use a DTMF receiver IC. One common DTMF receiver IC is the Motorola MT8870 that is widely used in electronic communications circuits. The MT8870 is an 18-pin IC. It is used in telephones and a variety of other applications. When a proper output is not obtained in projects using this IC, engineers or technicians need to test this IC separately. A quick testing of this IC could save a lot of time in research labs and manufacturing industries of communica.......

Telephone Interface (updated 12/30/09)

This project describes an Arduino/MCU interface to a telephone land-line. It's only been tested on a US version of the telephone system, but hopefully it will apply to the phone system in other countries. The basic idea was to allow the MCU to make calls by transmitting DTMF tones, and to receive and decode DTMF tones (keystrokes) made on the phone that was called.There are other possibilities however. Using the complete interface, it should be possible for the MCU to answer calls, and to transm.......
