When BJTs are used in digital circuits they usually operate in the: a. active region b. breakdown region c. saturation and cutoff regions d. linear region   2. Often a common-collector will be the last stage before the load; the main function(s) of this stage is to: a. provide voltage gain b. provide phase inversion (Inverting) c. provide a high-frequency path to improve the frequency response d. buffer the voltage amplifiers from the low-resistance load and provide impedance matching for maximum power transfer
