Laser Engineered Net Shaping (LENS) is a powder-based Additive Manufacturing process used for direct metal deposition. It operates using a high-power laser and metal powder feed system. In this process, a focused laser beam creates a molten pool on a metallic substrate. Simultaneously, metal powder is delivered through a nozzle into the melt pool. The injected powder melts instantly and solidifies upon cooling, forming a metallurgically bonded layer.
Answer: A Bezier surface is a parametric surface used in computer-aided design for modeling smooth and curved shapes. It is an extension of the Bezier curve into two parameters, generally represented by u and v. A Bezier surface is defined by a grid of control points that influence the shape of the surface. The surface does not necessarily pass through all control points, but its shape is controlled by them.
Bezier surfaces use Bernstein polynomials for mathematical representation.

Information Source
It generates the message or information to be transmitted.
The message may be voice, image, video, text, or data.
Example: Human voice in mobile communication.
2️⃣ Transmitter
The transmitter converts the message signal into a suitable electrical signal for transmission.
Functions of transmitter:
Amplification
Modulation
Encoding
It prepares the signal for long-distance transmission.
3️⃣ Channel
The channel is the medium through which the signal travels from transmitter to receiver.
