Thank.I have use prescaler frequency IC.I use MC12079 but only divider 256 factor.I want divide down to measured frequency of microcontroller .what method you known ?
2GHz / 256 = 7.8MHz, which is within the range of many MCUs. There are plenty of projects online that show how to use a PIC to measure up to 50MHz. If your 256 prescaler is used it would allow measurement up to 12.8GHz.
My Project is measure a bandwidth frequency interval a time not a sigle frequency.And use FFT algorithm.Therefor i cảnt use couter to measure frequency.I want divider with factor higher than to work easy.Thanks!
