The system and method enable simpler analog processing in a transmitter by reducing the number of bits in a digital signal through delta sigma modulation. The apparatus is referred to as a transforming or bag opening machine and includes a separation station and may include a perforation station and a piercing station. The method includes validating the calibration vector by comparing an anteroposterior axis to a threshold, wherein activity of the user is monitored using the validated calibration vector. Then, the output DC voltage is the summation of the input DC voltage and the capacitor voltage. The results are compared to determine a count how many memory cells showed a different result between the two reads.
