  Analogue  \An"a*logue\  (?;  115),  n.  [F.  ?,  fr  Gr  ?.] 
  1.  That  which  is  analogous  to  or  corresponds  with  some 
  other  thing 
 
  The  vexatious  tyranny  of  the  individual  despot  meets 
  its  analogue  in  the  insolent  tyranny  of  the  many 
  --I.  Taylor. 
 
  2.  (Philol.)  A  word  in  one  language  corresponding  with  one  in 
  another;  an  analogous  term;  as  the  Latin  ``pater''  is  the 
  analogue  of  the  English  ``father.'' 
 
  3.  (Nat.  Hist.) 
  a  An  organ  which  is  equivalent  in  its  functions  to  a 
  different  organ  in  another  species  or  group  or  even 
  in  the  same  group  as  the  gill  of  a  fish  is  the 
  analogue  of  a  lung  in  a  quadruped,  although  the  two 
  are  not  of  like  structural  relations. 
  b  A  species  in  one  genus  or  group  having  its  characters 
  parallel,  one  by  one  with  those  of  another  group 
  c  A  species  or  genus  in  one  country  closely  related  to  a 
  species  of  the  same  genus,  or  a  genus  of  the  same 
  group  in  another:  such  species  are  often  called 
  representative  species,  and  such  genera, 
  representative  genera.  --Dana. 
 
  From  WordNet  r  1.6  [wn]: 
 
  analogue 
  adj  :  (electronics)  of  a  circuit  or  device  having  an  output  that 
  is  proportional  to  the  input;  "analogue  device"; 
  "linear  amplifier"  [syn:  {analog},  {linear}]  [ant:  {digital}] 
  n  :  something  having  the  property  of  being  analogous  to 
  something  else  [syn:  {analog},  {parallel}] 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  analogue 
 
    (US:  "analog")  A  description  of  a  continuously 
  variable  signal  or  a  circuit  or  device  designed  to  handle  such 
  signals.  The  opposite  is  discrete"  or  "{digital}". 
 
  Analogue  circuits  are  much  harder  to  design  and  analyse  than 
  digital  ones  because  the  designer  must  take  into  account 
  effects  such  as  the  gain,  linearity  and  power  handling  of 
  components,  the  resistance,  capacitance  and  inductance  of  PCB 
  tracks,  wires  and  connectors,  interference  between  signals, 
  power  supply  stability  and  more  A  digital  circuit  design, 
  especially  for  high  switching  speeds,  must  also  take  these 
  factors  into  account  if  it  is  to  work  reliably,  but  they  are 
  usually  less  critical  because  most  digital  components  will 
  function  correctly  within  a  range  of  parameters  whereas  such 
  variations  will  corrupt  the  outputs  of  an  analogue  circuit.
