how do you analyse a binary time series using labview?

[elegans]

I am new with time series data analysis and labview. I was wondering if anyone could help me out with analyzing a binary time series (1 or 0 output) using labview. ecifically I want to find out the period/frequency of a
oscillating signal. Can I use the Walsh transform. If so how do I convert 'sequency' to time period. Are there any beginners text book out there? I would reallly appreciate it if anyone could help me out with this.
