    ADC_DELSIG fast filter?

      In ADC_DelSig manual page 4 there is a note related to Fast Filter conversion type:

         

      Note Care should be taken when switching signals between ADC conversions. Either
      switch the input quickly with hardware control or Stop the ADC while switching the input
      then restart the ADC after the new signal has been connected to the ADC. Failure to do
      this may result in crosstalk between signals in the ADC results.

         

      Does anyone know what Author had in mind saying "fast hardware switching"?

         

      Regards

          Switching between different channel can be done using AMUX(Analog Mux Component). There is a hardware mux component which switches between the input channels.

             

          So if the Hardware Mux is connected to ADC_Delsig, switching between input channels can be done very fast, in PSoC.
