Question 326

Boolean Algebra, Minimization of Functions

Appeared in Year: 2018 (UGC-NET)

Question

Assertion-Reason▾

Assertion(Ꭺ)

Emitter-Coupled logic (ECL) is the fastest of all logic families and used in application where very high speed is essential. (July)

Reason(Ꭱ)

High speed ECL is because the transistors are used in difference amplifier configuration in which they are never driven into saturation and the storage time is eliminated.
