Text: PRELIMINARY APPLICATION NOTE H8/300L PWM Producing DTMF Signal DTMF Introduction Dual Tone Multi-Frequency (DTMF) is generally used for telephony application. In the case when the MCU does not carry a DTMF generator, a software implementation can be achieved by using the Pulse Width Modulation (PWM) module of the MCU.
