Q1 (a) — Explain signal transformation needed for transforming independent variable for continuous-time signals.

Signal transformation changes the independent variable (usually time) to modify or analyze signals.

Common transformations:

1. Time shifting: shifts signal by .

2. Time scaling: compresses (if ) or expands (if ).

3. Time reversal: flips signal around the vertical axis.

These transformations help in synchronization, modulation, and system analysis in telecommunications....

Solar Cells-A solar cell (or photovoltaic cell) is a device that converts solar energy (sunlight) directly into electrical energy using the photovoltaic effect. It is made of semiconductors like silicon (Si), sometimes doped with phosphorus and boron to form a p–n junction. When sunlight falls on the junction, electrons move from the n-type to the p-type region, creating an electric current. Solar cells are clean, renewable, and require very little maintenance. They are widely used in solar panels,

Science

  • Equation:
    6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂ (light + chlorophyll)

  • Where: in chloroplasts (mainly leaf cells).

  • Purpose: Converts light energy → chemical energy (glucose).

  • Reactants: Carbon dioxide (air), water (roots)

  • Products: Glucose (used/stored), oxygen (released)

  • Uses of glucose:

    • Respiration (energy)

    • Stored as starch

    • Cellulose (cell walls)

    • Fats and oils (seeds)

    • Proteins (with nitrates)

  • Limiting factors: light intensity, temperature, CO₂ concentration, water, and chlorophyll.

KEVLAR-Kevlar is a strong, lightweight synthetic fiber made from a polymer called poly-para-phenylene terephthalamide. It is formed by polycondensation of p-phenylenediamine (C₆H₄(NH₂)₂) and terephthaloyl chloride (C₆H₄(COCl)₂). It has high strength, is lightweight, heat resistant, tough, and durable. It is used in ropes, cables, tires, sports equipment, and bulletproof vests. TERYLENE (DACRON)-Dacron or Terylene is a strong, wrinkle-free synthetic polyester fiber used in fabrics,
