Suppose that a 3-digit BCD digital-to-analog converterhas a full- scale output of 49.95mA. How many possible outputcurrent steps can this DAC produce?
A particular tachometer displays engine RPMs from zero to10,000.If the ADC accepts voltage levels from zero to fivevolts,in order to achieve full-scale representations from thetachometer, what should the output voltage be at 8500 RPM?
