SOLUTION 1:
Direction of current flow is shown 
Consider the following connection and rotating the wheel clock wise each time: 
Case 1: 
The given original position: 
Applying KCL
 

 

 

 
 
Solving the equation:
Case 2: 
Applying KCL
 

 

 

 
 
Solving the equation:
Case 3: 
Applying KCL
 

 

 

 
 
Solving the equation:
Case 4: 
Applying KCL
 

 

 

 
 
Solving the equation:
Hence highest value of X is 2.667V
5V 
-1V 
1V 
3V 
Solution 2: 
Let the voltage across the diodes be V1 and V2 
Hence current in the diode will be I1 and I2 
     ( 
 
     ) 
      ( 
  
       ) 
     
              
     
              
Applying KVL:
         (  
                             )
      (                               )                         
          
   (  
      )
       
   (  
      )                       
Hence solving them in matlab 
We get
Therefore current is: 
     
    (            )               
     
    (            )               
Hence now the voltage
Solution 3: 
(Please check saw tooth looks as shown bellow:)
i)  
Let the time period be T 
Hence we find the slope of the line:
