Correct Answer : Option (C) : Diode
Explanation : DTL stands for Diode Transistor Logic, where the diode serves as the Input network, and the switching operation is performed by the transistor. DTL is a predecessor of TTL (Transistor-Transistor Logic). The logic functions can be performed using resistors for biasing, transistors to amplify and diodes to switch and isolate inputs, producing logic levels.
