8.16, shows the block diagram of a digital multimeter (DMM) : l In the aA.C. voltage modea, the applied input is fed through a calibrated, compensated attenuator, to a precision full-wave rectifier circuit followed by a ripple reduction filter. The resulting D.C. is fed to ADC and the subsequent display system. l For current measurements, the drop across an internal calibrated shunt is measured, directly by theanbsp;...
