i read in television reception that to detect horizontal and vertical sync pulses we use differentiator and integrator . but when i saw the diagram they were nothing but low pass and high pass filters. so do differentiator and integrators are nothing but filters or is there a difference.
 

Re: differentiator-hpf

I think Differentiators are simply high pass filters. By increasing the order of the filter we also increase the order of differenciation.
 

differentiator-hpf

What thedesolatesoul wrote can confirmed by the Laplace transform differentiation property:

df(t)/dt ->L-> S*F(s)
d2f(t)/dt2 ->L-> S^2*F(s)
and so on...
