how to calculate frequency
i want to ask a question regarding the measurement of the frequency
i am looking for a particular signal
the signal to noise ration is not very high
i am detecting the presence of the signal via measuring the amplitude of signal
whenever the strength of the signal is higher then noise level , infact quite high
then i can detect the presence of the signal
one question arouse in my mind
to detect the signal via frequecny
how can i calculate the signal frequency ?
as if i am able to judge the frquency of the signal i might use tone detector circuitory
also i read about the PLL
can any one suggest me some book where the use of PLL circuit for differnct application is listed
books tells how PLL work , how it is made but I want to learn that how can i use PLL ic for differnt application
