A Special case:

When,  is constant,

 
 
 
 

One can show a wide band amplitude reduction of the primary mass (X1) by suitably choosing ka and kb in equation (19.11)


 
       

Numerical exercise:

Consider,


 
,   ,      
 

Find out the Transfer function and plot.

Congratulations! You have finished Lecture 19.
