Preferred Abstract (Original): 
Two iterative analysis algorithms were developed for the reoptimization of the LP synthesis filter based on a pulse-by-pulse reoptimization manner. In this study, the use of the pitch filter in the analysis algorithms is introduced. Similar to the no pitch case, improvement in the gain is achieved. On the other hand, this gain has dropped compared to the no pitch case. Moreover, the number of pulses needed to reoptimize the LP filter found to be much less than that, in the no pitch case.
