1. A 12-bit AID converter has an input range of -5 to +5 V. Estimate the quantization error (as a percentage of reading) for an input -2.46.
2. 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 mV? Could you attenuate the signal before amplification to reduce the quantizing error?
