  13.  I'm interested in designing a circuit that will determine
  14.  if a sine wave frequency is in a certain range of values,
  15.  specifically, 45-51 MHz.  It is very important that the
  16.  detector be as reliable a possible, so I would like to use
  17.  only a few active components and try to stick to RC's as
  18.  much a possible.
  19.  
  20.  Any suggestions would be welcome.
