N2 - A novel algorithm is presented to calculate the most appropriate frequency multipliers for the conversion of NBFM to WBFM. This algorithm makes the communication system designer job easier and calculates most accurately the best possible frequency multiplying factors in least possible time. The carrier frequency and frequency deviation of NBFM signal can be increased by the application of these frequency multipliers. The algorithm is implemented in C++ programming language and is applied to various practical design problems. The best possible results are generated with least possible errors. The algorithm can be used for either frequency Doublers or frequency Triplers or frequency Quintuplers or 1000* frequency or combination of them like frequency Doublers and Triplers, frequency Doublers and Quintuplers, frequency Triplers and frequency Quintuplers, etc.
