Thank you FvM for your answer, it means if I dont want to distore the signal I should design the amplifier with slew rate equal to 189 V/uS at least,,,
only please I need the source of this calculation so I can discuss it with my professor.

it means if my amplifier has 30 MHz bandwidth doesnt mean I can use the full range as the gain will drop,,,, so what is the meaning of having this value in our design if we cant use it .....is there a relationship between GBW and slew rate ??
