Sierpinski Triangle of Level 02

Objective:- To create a Sierpinski Triangle of Level 2 with proper dimensions

A Sierpinski triangle, named after the Polish mathematician Wacław Sierpiński, is a fractal shape that is self-similar and is constructed through an iterative process. Each iteration involves subdividing equilateral triangles into smaller triangles and removing the central triangle. Here's how you can construct a Sierpinski triangle of level 2:

Sierpenski Triangle of Level 02

  • Start with a large equilateral triangle.
  • Divide the large equilateral triangle into four smaller congruent equilateral triangles by connecting the midpoints of its three sides.
  • Remove the central triangle.
  • You're left with three equilateral triangles arranged in the shape of a larger equilateral triangle. Repeat steps 2 and 3 for each of these smaller triangles.
By completing these steps, you'll create a Sierpinski triangle of level 2. It's worth noting that each iteration increases the complexity of the fractal, and as the level increases, the triangle becomes more intricate and detailed.

Electronics

Objective:- To design circuits for Basic Gates(AN R) using an NPN Transistor.

Creating an AND gate using NPN transistors is a common application of transistor logic circuits. Here's a basic schematic and explanation of how you can implement an AND gate using NPN transistors:
Components Needed:
  • Two NPN transistors (e.g., 2N2222, BC547)
  • Resistors (for biasing)
  • Power supply (Vcc)
  • Input signals (A and B)
  • Output signal (Y)

Operation:
  • When both input signals A and B are high (logical 1), both transistors T1 and T2 will be in the conducting state.
  • This allows current to flow through T1 and T2, pulling the output signal Y to ground (logical 0).
  • If either input A or B (or both) is low (logical 0), at least one of the transistors will be off, and the output signal Y will be pulled high (logical 1) through the collector resistor.
Creating an OR gate using NPN transistors involves combining the outputs of multiple transistors to produce an output signal that is high (logical 1) when any of the input signals are high. Here's a basic schematic and explanation of how you can implement an OR gate using NPN transistors:
Components Needed:
  • Two NPN transistors (e.g., 2N2222, BC547)
  • Resistors (for biasing)
  • Power supply (Vcc)
  • Input signals (A and B)
  • Output signal (Y)

Operation:
  • If either input signal A or B (or both) is high (logical 1), the corresponding transistor will conduct, allowing current to flow through it.
  • When current flows through any of the transistors, the output signal Y will be pulled low (logical 0).
  • If both input signals A and B are low (logical 0), neither transistor will conduct, and the output signal Y will be high (logical 1) through the pull-up resistor.

N- Channel Mosfet

Objective:- An N-channel MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of field-effect transistor where the conducting channel is formed by the flow of electrons (hence the term "N-channel") between the source and drain terminals.

Working:-
Operation:
  • When no voltage is applied to the gate terminal (Vgs = 0), the MOSFET is in the off state, and there is minimal current flow between the source and drain terminals.
  • When a positive voltage is applied to the gate terminal with respect to the source terminal (Vgs > Vth, where Vth is the threshold voltage), it creates an electric field that attracts electrons from the N-type substrate to form a conductive channel between the source and drain.
  • As the gate voltage increases beyond the threshold voltage, the channel conductivity increases, allowing more current to flow from the source to the drain.
  • The amount of current flowing through the channel (from source to drain) is controlled by the voltage applied to the gate terminal. Increasing the gate-source voltage (Vgs) increases the conductivity of the channel and hence the drain current (Id).
  • The MOSFET operates primarily in the saturation region, where the channel is fully formed and the drain current is relatively insensitive to changes in drain-to-source voltage (Vds).
