Suppose, you want to send three signal (cos or sin wave) through a transmission medium. Second and third signals are 30 degree and 60 degree shifted from the first signal respectively. and. Amplitude of the signals are AMP1, AMP2 and AMP3 respectively. Frequency of the signals are FREQ1, FREQ2 and FREQ3 respectively. 1. Plot the composite signal in both time and frequency domain in a figure titled "Input signal. In the figure use subplot to show all signals in time domain, composite signal in time and frequency domain. Use valid label in x-axis & y-axis. 2. Quantize the composite signal in 16 equally distributed levels and show only 2 cycle in a new figure titled "Quantized Signal". Use valid label in x-axis & y-axis. 3. During the transmission, Signal suffered unwanted noise with amplitude of 0.2 V. Also consider the first signal produced 2nd harmonic with (1) th of the main signal amplitude. 8 Now calculate Bandwidth with and without impairments, SNR, SINAD, Max. capacity of the signals, No. of level. 4. Show the results in following format: [Bandwidth with SNR, THD Max. Capacity SNR Bandwidth without SNR,THD] No. of Level SINAD AMP1 = 38 FREQ1= 183 AMP2 = 86 FREQ2=386 AMP3=66 FREQ3=666 Instructions: 1. Please use MATLAB software to accomplish the project.
