Can Step up transformer amplify signals?

[bukks bunny]

When all you need is increased amplitude of a voltage signal and when the pass-band is narrow then a transformer can be used.

As the prime concern was increasing the voltage amplitude(voltage gain) i guess i could use a step up tranformer in circuits where size doesnot matter.

Do you 'have a thing' about transformers?
It is possible to knock a nail in a piece of wood, using a pickaxe but why would you want to?
Whilst there are occasions when all sorts of alternatives can be used to achieve a result, why not think in terms of using the standard approach? As I said before, there may be good reasons why you should not use a transformer in some circumstances. Wide-band transformers are very problematic and, of course, have infinite insertion loss at DC. They have their place but they are not amplifiers - end of.
