The divergence can be positive, negative, or zero, indicating whether there are sources, sinks, or neither of the vector field at that point.

15Tarique_DSP_8ETC.PPTSadorYonas FFT is an efficient algorithm to compute the discrete Fourier transform (DFT) and convert a time domain signal to its frequency domain representation. Radix-2 FFT is the most common algorithm, in which the input is divided into groups of 2 samples at each stage. FFT algorithms generally have a number of samples that is a power of 2, like 2N, to efficiently compute the DFT. The radix-2 FFT breaks the computation into "butterflies" or decimation in time (DIT) and decimation in frequency (DIF) structures to recursively compute the DFT. Twiddle factors representing complex roots of unity are used to compute the outputs of each butterfly operation.

raster and random scan
raster and random scanSonia Pahuja Raster scan displays have lower resolution than random scan displays because raster scan stores picture definition as intensity values along scan lines, while random scan stores pictures as line commands. Raster scan directs its electron beam from top to bottom across the entire screen one row at a time, making it less expensive than random scan which only draws required lines. However, random scan produces smoother lines and can provide more realistic displays through advanced techniques like shadows and hidden surfaces.
Graphics exercise (b.tech)
Graphics exercise (b.tech)Sonia Pahuja This document describes the algorithm for drawing a circle by determining pixel positions. It explains that if the midpoint calculation is inside the circle, the pixel on the current scan line is used, otherwise the pixel on the previous scan line is used. It then states that symmetry points are determined in the other octants and each pixel position is moved to the circular path centered at (xc, yc) by adding those coordinates before repeating until x is greater than or equal to y.
graphics notes
graphics notesSonia Pahuja The document describes the Phong shading model for modeling specular reflections. It explains that specular reflection results from total or near-total reflection of incident light in a concentrated region around the specular reflection angle. The Phong model sets the intensity of specular reflection proportional to the cosine of the viewing angle raised to a power 'n'. Higher values of 'n' produce shinier surfaces, while lower values produce duller surfaces. The model calculates specular reflection based on vectors representing the light source, viewer, and specular reflection direction.

The Surajkund reservoir was later refurbished during the rule of Feroz Shah Tughlaq in the 14th century. Since 1987, the Haryana government has organized the annual Surajkund Crafts Mela at the site in February-March, featuring artisans and craftspeople from all over India alongside food stalls highlighting various regional cu
Business Ethics 
Business Ethics Sonia Pahuja Business ethics are moral principles that guide how a business operates. They include transparency, fair competition, upholding employee rights, health and safety, corporate citizenship, and avoiding conflicts of interest. Upholding strong business ethics builds trust with stakeholders and protects a company's reputation. The film Guru depicts the business world of India in the 1980s as unethical, where one had to resort to actions like bribery and tax evasion to succeed due to unfair laws and obstacles faced. However, the film also shows that achieving success may require navigating ethical dilemmas, and that the intention should be to operate honestly and accountably.

Notation includes braces { } to list elements and vertical bars for set builder notation. A is a subset of B if all elements of A are also in B, written as A ⊆ B. The union of sets A and B contains all elements that are in A or B, written as A ∪ B. The intersection of sets A and B contains elements that are only in both A and B, written as A ∩ B.
