Diff-amp is basically designed as DC-amplifier so that it
will be suitable for IC fabrication .Also the lower
frequency response is also improved.Taking i/p as
difference of 2signals is required so as to eliminate noise.

Diff amp is one of the stages of the Op-amp.Op-amp is
having very high gain which is obtained by using diffamp
transistors as darlington pair and their gain beta is
increased by punch through effect.

Is it ok, to use non-contact type Radar type LT, on a tank that is half circular from the bottom side? If yes the, isn't the waves gonna bent in other directions?
