Answer to Question #65550 in Electrical Engineering for lilonas

Question

Phase Modulation
a) Calculate the following parameters for a Phase Modulator which has a carrier frequency of 10 kHz and a modulating data rate of 3 kHz:
i. Carrier time period:
ii. Modulating data time period:
iii. Baud rate:
iv. Upper sideband:
v. Lower sideband:
vi. Bandwidth:
Note: show all calculations used.
b) Use Labview to build a Phase Modulator. The sinusoidal carrier signal should be adjustable up to 10 kHz and the amplitude adjustable to 5 volts, using a “simulate signal” express vi.
The modulating input should be a simulate signal vi configured as a square wave in order to provide digital modulating data. The square wave frequency should be adjustable to 5000 Hz and its amplitude adjustable to 5 volts.
The output should be displayed in the time and frequency domains using suitably configured and labelled waveform graphs. Ensure the Front Panel Layout conforms to proper HMI design guidelines.
Provide screenshots of the front panel which clearly display Phase Modulation in operation using the digital modulation data generated. Explain in your own words the displays provided.
c) Use the Labview circuit to verify the calculations in part (a). Provide screenshots with explanations to confirm the results. Explain any discrepancies.Convolve the following two sequences
