Perhaps you need a better tutorial?
If you understand how to do math in the Laplace domain, then the above
statement should just fall out. If you don't understand how to do math
in the Laplace domain -- find out.

Don't learn anything from tutorials.

Hi,
I am learning PLL from a tutoril. It says the zero has the character,
see below. The zero has the transfer function value 0, but I cannot
arrive the conclusion below. Could you explain it to me more? Thanks
in advance.
.....................
The �Zero� in the numerator of the closed-loop
transfer function is the frequency in radians/s
where the gain of the integral and proportional
paths are equal.
