DTMF Decoder Using MT8870 Electronics DIY This circuit detects the dial tone from a telephone line and decodes the keypad pressed on the remote telephone. The dial tone we heard when we pick up the phone set is call Dual Tone Multi Frequency, DTMF in short. MT8870 DTMF Telephone Dial Tone Decoder Electronics DIY 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. Phone to Microcontroller interfacing with DTMF – uCHobby Mayank shows us how to interface a microcontroller to the phone line. The tones you hear as you enter numbers on your phone can remotely control devices. Circuit Zone Electronic Projects, Electronic ... I needed a way to extract audio from a phone line for my DTMF decoder. I found a site full of examples on how to do it, and I built an interface that suited my needs: RCA output, with a signal strong enough to be fed directly to an audio amplifier or line in. DTMF Paging System using ASK and FM transmitter receiver. It's a digital AM transmitter. The transmitter receiver set uses amplitude shift keying to send the DTMF tones. This is not picked up by the FM radio, so for fun I put a speaker 2.5mm plug to the DTMF decoder for the handheld.
