Abstract :
A low-power microprocessor-controlled data-acquisition system, using nonvolatile bubble memory cartridges for mass data storage, is described. The system is battery powered and can operate unattended in a field environment for two months. An analog voltage, which is derived from a gamma-ray ionization chamber or other moderately high-output transducer, is the system input. By using CMOS technology and power switching techniques, the system achieves very low power consumption (<10 mW)
