Hi All
I have a task to measure a low frequency signal (about 30kHz) with an accuracy of 2ppm.
I'd like to have frequency readings at least twice per second. So I can't just count the input signal for a period of time as that would entail counting for over 30s to get the accuracy.
I have a plan to use a counter (say 10MHz) and measure say 10000 input periods. I'm sure this gives me the accuracy, and also provides enough readings per second.
But are there other methods?
