An active high pushbutton switch input circuit has a poorly performing pushbutton characterized by a measured resistance of 100,000 ohms when open (not button is not pushed) and 1000 ohms when closed (the button is pushed). The fixed resistor in this circuit has a measured value of 10,000 ohms. If the reference logic level voltages are +5 volts and 0 volts, what are the voltages of Outputbutton_pushed and Outputbutton_not_pushed?
