Hi,
Can anybody explain for me why 1st order PLL has smaller transient duration than 2nd order loop for the same value of loop noise equivalent bandwidth??
This is the model I am trying to simulate in matlab . Here F(Z) is is a digital filter.
What I mean by first order loop is F(Z) = A i.e. any constant(obtained from loop bandwidth)
and
for 2nd order loop F(Z) = (aZ-b)/(Z-1). a and b also obtained from loop bandwidth and damping ratio.
Thanx
