Question

exlpain the type of delay line​

Answer 1

Answer:

HEY Buddy here's ur answer

• Passive delay lines or analog delay lines (ADL) are built with analog components and can delay both analog and digital signals. They attenuate the signal from input to output and use components such as capacitors and inductors.

• Active delay lines or digital delay lines (DDL) are built with digital components and are used to delay only digital signals. Active delay lines do not attenuate the signal from input to output, and are characterized by a specific logic family. Common logic families include transistor-transistor logic (TTL), complementary metal-oxide semiconductor (CMOS), and emitter-coupled logic (ECL).

• Fixed delay lines can delay signals by a time interval set by the manufacturer. For fixed delay lines, the delay time is the only delay time that can be set.

• Variable delay lines can delay signals between two values in a specified range. Generally, the low end of the range is zero. For variable delay lines, the delay time is the upper value of a tapped or programmable delay range.

Answer:

hope it helps you out

please mark it as brainliest and follow me

Explanation:

There are two basic delay line types: fixed and variable.

Fixed delay lines can delay signals by a time interval set by the manufacturer. For fixed delay lines, the delay time is the only delay time that can be set.

Variable delay lines can delay signals between two values in a specified range.
