Re: Frequency measurement
i dont know whether it is just for measuring or calculating using a processor.
if just measure:
use a scope. find the period. and measure the freq.
modern dso can display that value also.
if for using a processor to calculate:
method is same.
measure the period between the similar instants.
e.g, use zero cross detector . you know the half period . and calculate
the freq.
if the exact environment is specified somebody will help.
