b. Resonance characteristics of microstrip ring resonator and computation of dielectric constant of the substrate.

c. Power division and isolation of microstrip power divider.

8. Measurement of propagation loss, bending loss and numerical aperture of an optical fiber.

PART-B: Simulation Experiments using SCILAB/MATLAB/Simulink or LabView

1. Simulate NRZ, RZ, half-sinusoid and raised cosine pulses and generate eye diagram for binary polar signaling.

2. Simulate the Pulse code modulation and demodulation system and display the waveforms.

3. Simulate the QPSK transmitter and receiver. Plot the signals and its constellation diagram.

4. Test the performance of a binary differential phase shift keying system by simulating the non-coherent detection of binary DPSK.

Course outcomes:

On the completion of this laboratory course, the students will be able to:

Determine the characteristics and response of microwave devices and optical waveguide.
Determine the characteristics of microstrip antennas and devices and compute the parameters associated with it.
Simulate the digital modulation schemes with the display of waveforms and computation of performance parameters.
Design and test the digital modulation circuits/systems and display the waveforms.

Conduct of Practical Examination:

All laboratory experiments are to be considered for practical examination.
For examination one question from PART-A and one question from PART-B or only one question from PART-B experiments based on the complexity, to be set.
Students are allowed to pick one experiment from the lot.
Strictly follow the instructions as printed on the cover page of answer script for breakup of marks.
Change of experiment is allowed only once and Marks allotted to the procedure part to be made zero.
