#161866 - Frequency Multiplication |
Hello
I want to know how to multupiler the frequncy by say 3.456677; I mean fout=(float no(1.000000 to 9.999999))fin It possible using MCU or Some other techniquie like VLSI. I know using PLL it can be achive but using PLL but proble good soluation in this case. Example fout=3.456677fin So I have to multiplication of input frequency By 3456677 By PLL COUNTER METHOD and to get 3456677*Fin Now to get desire frequency again divide it by 1000000 using COUNTER to get Fin*3.456677. Which is not better soluation. Pl.Note that My Fin is about 100KHz. Ignor my poor engilsh. I hope you will undersatnd what I want to Say regards satish munot |

| what is the wave form shape of the original signal? | 01/01/70 00:00 | |
| Yes, PLL is the most promising solution | 01/01/70 00:00 | |
