1. The voltage indicated by a 0- to 5-kg strain gauge balance scale is expected to vary from 0 to 4 mV. The signal is to be recorded using a 12-bit A/D converter having a +5-V range with the weight displayed on a computer monitor. a- Suggest an appropriate amplifier gain for this situation b- What would be the resolution (in kg) after you add an amplifier with a gain of G-38 dB?
