  Frequency Shift Keying
  FSK
  
     <communications> (FSK) The use of frequency modulation to
     transmit digital data, i.e. two different carrier
     frequencies are used to represent zero and one.
  
     FSK was originally used to transmit teleprinter messages by
     radio (RTTY) but can be used for most other types of radio
     and land-line digital telegraphy.  More than two frequencies
     can be used to increase transmission rates.
