gain = output voltage / input voltage.
dc = constant voltage level.
output of the integrator goes infinite when a constant input voltage is applied --> gain = infinite / input voltage = infinite.
Hi Jackg,
It is not related with bandwidth nor with averaging.
The relation gain=output/input is to be thaught when the output reaches steady state.
Maybe you are confused by the fact that an ideal integrator never reaches steady state (otherwise stated, it takes an infinite time). But in the limit (when t->infinity) the ouput goes to infinity for any (nonzero) d.c. input.

Hi!
what does infinite dc gain exactly mean in case of ideal integrator?
Thank you,
jackg
