Analysis of Circuits lab report

This project involves the analysis and verification of two-port networks using Z-parameters (impedance parameters) and Y-parameters (admittance parameters). The experiments involved measuring these parameters for T-network and π-network configurations and comparing theoretical values with measured values obtained through LTSpice simulation.

Why was it created?

• To verify the theoretical analysis of two-port networks by comparing them with practical measurements.
• To gain hands-on experience with two-port network analysis and the use of measurement instruments.
• To understand the application of these parameters in amplifier and filter design.

How does it work?

Z-parameter Analysis:

• The Z-parameters were calculated and verified by performing open-circuit and short-circuit tests on the T-network and π-network circuits.
• Impedance values were measured using the LTSpice simulation and compared with theoretical values.

Y-parameter Analysis:

• The Y-parameters were measured by short-circuiting the input and output ports and calculating the admittances.
• The LTSpice software was used to simulate the circuits under different voltage conditions (5V, 10V, 15V).

Results Verification:

• Experimental results from the physical circuit setups were compared with theoretical values, demonstrating the accuracy of the parameters.
