Which of the Following Accurately Describes ECL

Multiple Choice

Which of the following accurately describes ECL?

A) ECL stands for energy- coupled logic; the input energy is amplified by the input transistors and allows the device to deliver higher output currents.
B) 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.
C) ECL stands for emitter- coupled logic; all of the inputs are coupled into the device through the emitters of the input transistors.
D) ECL stands for electron- coupled logic; all of the devices used within the gates are N- type transistors.
