Logic Circuits Interview Questions and Answers: 1. What is a combinational circuit? Ans. In a combinational circuit, the output depends upon present input(s) only i.e., not dependent on the previous input(s).…
What is Tristate Logic or Three State Logic Circuit? Tristate Logic or Three State Logic Circuit - In normal logic circuits there are two states of output, either low or…
Logic Circuit in Static Relay: The concept of Logic Circuit in Static Relay can be better understood by considering the logic operations performed by the devices rather than the actual…
Diode Logic Circuits: A Diode Logic Circuits produces an output voltage which is either high or low, depending upon the levels of several input voltages. The two basic logic circuits…
Integrated Injection Logic (IIL or I2L) Circuit: It is the latest entry into the bipolar saturated logic field. It uses no biasing and loading resistors at all. Resistors require lot…
What is Emitter Coupled Logic (ECL) Circuit? Emitter coupled logic (ECL) is the fastest of all logic families and, therefore, is employed in applications where very high speed is essential.…
What is Transistor Transistor Logic (TTL) Circuit? Texas instruments introduced transistor transistor logic (TTL), a widely used family of digital devices in 1964. It is fast, inexpensive and easy to…
What is Diode Transistor Logic (DTL) Circuit? Diode Transistor Logic (DTL) is also a saturated logic and uses diodes, resistors and transisÂtors. The circuit diagram is shown in Fig. 47.2.…
