  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.
