An AID converter uses 12 bits and has an input range of 1O
Chapter , Problem 4.27(choose chapter or problem)
An AID converter uses 12 bits and has an input range of 1O V. An amplifier is connected to the input and has selectable gains of 10, 100, and 1000. A time-varying signal from a transducer varies between +15 and -15 m V and is input to the amplifier. Select the best value for the gain to minimize the quantizing error. What will be the quantizing error (as a percentage of the reading) when the transducer voltage is 3.75 mY? Could you attenuate the signal before amplification to reduce the quantizing error?
