  21. C="Mux4: 4 Channel Multiplexer Model:
  22. Takes the 4-inputs in the \"top-down\" order in which they occur and apply them to the output every \"dt\" seconds.  If you need more channels, just add the extra inputs, set the parameter n equal to the number of inputs, duplicate the \"Ch. #\" compound blocks as required and feed their outputs to the summer.   
  23.  
  24. Limitations:
  25. 1.  Always verify that \"dt\"  is greater than the simulation time step. 
  26. 2.   Also the Channel counter circuit (which computes cc) may have counter overshoot (to n+1) when using RK2, trapeziodal, or Euler integrators- the term \"dt * .1\" fed to the summer is provided to prevent this, however, if it doesnt you may need to increase the \".1\" gain slightly.
