An air-conditioner (AC) will provide control of temperature in the range 60° to 100°F. Temperature information is input to a computer from a 6-bit ADC as value NT; that is, OOH (010) at 60°F and 3FH (6310) at 100°F. The setpoint is 75°F, the zero-error output is 50%, and the proportional gain is to be 8%/%.

The output goes to a 6-bit DAC for which OOH is AC off and 63H is AC maximum cooling. Specify the control equations that must be used. What is the resolution in tem-perature control?
