Q1. Types of Transmission Lines
Ans. 
Transmission lines are used to carry signals or power from one point to another.
• Types include coaxial cables, twisted pair cables, and optical fibers.

• Coaxial cables have a central conductor surrounded by an insulating layer and a metallic shield.

• Twisted pair cables consist of two insulated copper wires twisted together to reduce interference.

• Optical fibers use light to transmit data and are made of glass or plastic fib...read more

Q2. Diplexer vs Duplexer
Ans. 
A diplexer is a device that separates or combines different frequency bands, while a duplexer is a device that allows two-way communication over a single channel.
• Diplexer is used to separate different frequency bands in communication systems.

• Duplexer allows two-way communication over a single channel by separating transmit and receive signals.

• Example: Diplexer is used in satellite communication to separate uplink and d...read more

Q3. Phase delay vs Group delay
Ans. 
Phase delay is the time difference between input and output signals, while group delay is the rate of change of phase delay with respect to frequency.
• Phase delay is the time delay experienced by a signal passing through a system, while group delay is the derivative of phase delay with respect to frequency.

• Phase delay is constant for all frequencies, while group delay varies with frequency.

• In audio systems, phase delay ...read more

Q1. How to optimize build in Angular?
Ans. 
Optimizing build in Angular involves reducing bundle size, enabling lazy loading, using AOT compilation, and leveraging tree shaking.
• Reduce bundle size by removing unused code and optimizing imports

• Enable lazy loading to load modules on demand instead of all at once

• Use Ahead-of-Time (AOT) compilation to pre-compile templates and reduce runtime overhead

• Leverage tree shaking to eliminate dead code and reduce bundle size
