Which of the following accurately describes ECL?
 
  A) ECL stands for emitter-coupled logic; all of the inputs are coupled into the device through the emitters of the input transistors.
  B) ECL stands for electron-coupled logic; all of the devices used within the gates are N-type transistors.
  C) ECL stands for energy-coupled logic; the input energy is amplified by the input transistors and allows the device to deliver higher output currents.
  D) ECL stands for emitter-coupled logic; all of the emitters of the input transistors are connected together and each transistor functions as an emitter follower.
