Analog and Digital are Not Mutually Excusive

nickgray

Many things can be accomplished with either analog or digital techniques, but any given application can best be done with one or the other, usually. There are places for analog and places for digital and there really should be no argument about that.

    HI  NICK !

     

    I   THINK  IT IS  OVERSAMPLING   AS,  SINCE   FREQUENCY  SAMPLING   IT   IS   RF/IF

    AND   RF/IF   MORE   EXCEED  FREQUENCY AM.

    Hi Vikttor,

    I am not sure to what you are referring because undersampling converters are already used for a combination of digitization and RF detection. A converter used in a high Nyquist zone will convert the digitized signal to frequencies in the first Nyquist band, thus providing RF detection and digitization at the same time. The advantage of this detection (or demodulation) is avoiding the non-linearity of other demodulation schemes.

     

    Can you describe further just what you mean?

  • HI  NICK!

     

    I  WANT  TO  KNOW  YOUR  OPINION  ABOUT   NECESSITY  ADCs   with  function  RF  detector   today.

    TODAY  IN  DIRECT  CONVERSION  RECEIVERS     USE   QUADRATURE  SIGNAL  PROCESSIG  CALL   HOW  I/Q   SIGNAL  PROCESSING.

     

    MAY  BE  WE   DISCUSS    THIS   TOPIC  IN  YOUR  BLOG  ?

  • HI  NICK!

     

    I  THINK  ANALOG  EARLY  BURY.

    ANALOG  WOLD  ARROUD  US.DIGITAL  WOLD  CONVERSION. PROCESSING  AND  COMMUNICAT   ANALOG  CONTENT  FOR  US.

     

    LINKS  BETWEEN   ANALOG  AND  DIGITAL  WILL  DEVELOP  AND  PERFECT  NEW

    HIGH  LEVELS.

     

    I  DESIGNED  ADCs   with  function  amplitude  detector.

    THESE  ADCs  no  require  sample-hold  swich  and  anti-aliasing  filter.

    INPUT  SIGNAL   for  ADCs  is  RF, OUTPUT  SIGNAL  is  frequency  amplitude  modulation.

    THESE   ADCs   may  be  apply  for  direct  conversion  receivers,power  meters,chips  with  adaptive  signal   processing  ...

     

    I  WANT  TO  SEE  these   ADCs  as  high  technological  products.

    My point, which I thought was clear, is that there is a place for both analog and digital electronics. I wrote this in response to those who think that analog is not necessary and will eventually disappear. I doubt that the percentage of people who believe this is small, but the number of people who seem to believe this is large.
