    Filtering a signal

    volodymyr.hoy

       Project: ADC => DMA => Filter => DMA => DAC

         

      The input is provided as a DTMF waveform signal. The amplitude is in range 0.2 ..2.2 V.

         

      The problem is with output signal.  The waveform is rectangular(should be as a sine). It looks like the DAC is in saturation mode.

         

      Thanks.
