   Ripple

   So - in the case of a linear power supply - the rectified output of   
   the transformer typically goes straight to a big old storage cap for   
   smoothing purposes. My question is: how much ripple should I expect to   
   see across that cap if all's working well? I have to say I'm seeing a   
   *lot* of ripple on this cap in a Marconi RF signal generator and it's   
   finding its way to the RF output, which of course should ideally have   
   zero ripple on it. The aforementioned cap tests fine WRT ESR and   
   capacitance in-circuit, I should add.   
      
   Thanks,   
   CD.
