[time-nuts] Where do people get the time?

2022-01-09 Thread Thomas D. Erb
in the 1930's you could call the local telephone operator - who would look at the wall clock at say the "electric time is" . meaning the time the generator synchronous wall clock read. Thomas D. Erb p:508-359-4396 f:508-359-4482 a:97 West Street, Medfield, MA 02052

Hi, The traditional way is to lock an oscillator and look at the phase detector output. You get a high-pass filter from the locking, but for many purposes that's just fine. In some cases it is called "the golden PLL method". Cheers, Magnus On 2022-01-09 18:04, Marek Doršic wrote: Is

Is there any method to measure random jitter without TimePod or scopes costing a small fortune? .md > On 9 Jan 2022, at 01:21, Bruce Griffiths wrote: > > Yes, that post is full of misleading information. > The TI document is irrelevant as the PIC based divider doesn't have non >
