NBFM to WBFM Signal Conversion Analysis by sanatan is a document available to read on EtoBox.
A narrowband FM (NBFM) signal with a carrier of 200 kHz and peak deviation of 21.3 Hz is multiplied and mixed to produce a wideband FM (WBFM) signal with a carrier of 100 MHz and peak deviation of 75 kHz. To achieve this, the carrier must be multiplied by N1=500 and N2=3, and the intermediate frequency fO must be 98.5 MHz. A NBFM signal with a carrier of 100 kHz and deviation of 30 Hz is multiplied. After 5 doublers, the carrier is 800 MHz with a deviation of 120 Hz. After then passing through 3 triplers,
