    Hi all, wondering if anyone can offer any help with the above items, what i need to know is in what form both are used, why when you use the formula to work out frequency of oscillation there are two equations, both have 2∏RC on the bottom line but the √6 will be on either the top line or underneath, what defines where it needs to be and why?

    Is it for when you use a CR Network instead of an RC Network?
