In the block diagram of most instruments shown in my text books, I see an attenuator followed by an amplifier.
What is the need for this? Why not provide a lower gain amplifier without a preceding attenuator or a lower attenuation attenuator without a succeeding amplifier?
I have not found any satisfactory explanation for this anywhere.
Thanks in advance.
