  • Using PWM to Generate Analog Output
    Pulse Width Modulation (PWM) modules, which produce basically digital waveforms, can be used as cheap Digital-to-Analog (D/A) converters only a few external components. A wide variety of microcontroller applications exist that need analog output but do not require high resolution D/A converters
  • D/A Conversion Using PWM and R-2R Ladders to Generate Sine and DTMF Waveforms
    of complex analog waveforms.: (PWM and R-2R Ladder). Both the Pulse Width Modulation (PWM) and resistor ladders require only a few external components to create a D/A converter with the PICmicro? microcontroller series. These techniques can be used to generate dual-tone multiplexed frequencies (DTMF
