Straightforward implementation
    
      - Simulink implementation of Version A:
        
          - completely standard
 
          - define subcomponent for a class
            
              
 
              - uses UnitDelay to store
                xi(k)
 
            
           
          - complete model
            
          
 
        
       
      - Implementation of Version B:
        
          - create subsystem Binomial
            for random numbers ξ
            
              - ξ ~ B(n, p), p as parameter, n as input
 
              - easy with Matlab function
 
            
           
          - new class component
