hi i need some help on modulation, there are several part to the question and i will post them 1 by 1, you are more than welcome to take credit for all of them. thank you so much for your help!

this is for question 2 part 5

there are 10 questions total, 2 big question with 5 part each posted, each part of the question is posted separatly

Encoding table: Symbol Frequency 0000 1 Hz 0001 1 Hz 0010 1 Hz 0011 1 Hz 0100 1 Hz 0101 1 Hz 0110 1 Hz 0111 1 Hz 1000 1 Hz 1001 1 Hz 1010 1011 1 Hz 1100 1 Hz 1101 1 Hz 1110 1 Hz 1111 1 Hz Amplitude Phase 3.000.000 3.00 90.00 3.00 180.00 3.00 270.00 5.00 45.00 5.00 135.000 5.00 225.00 5.00 315.00 7.000.00 7.00 90.00 7.00 180.00 7.00 270.00 9.00 45.00 9.00 135.000 9.00 225.00 9.00 315.00 1 Hz Tasks: 1. Draw a constellation diagram for the modulation scheme using Desmos. Enter the URL of your saved Desmos constellation diagram in the following field: 2. Enter the coordinates of the following symbols of your constellation diagram in the table below: (8 marks) Symbol X Y 0000 0010 0011 0101 0111 1000 1011 1111 3. Draw a wave form for each symbol using Desmos. Enter the URL of your saved Desmos symbols in the follow- ing field: 4. Sample the symbols specified in the table below at the given X coordinates (using the plots you made in step 3). (4 marks) Symbol x 0000 OOI 001 0100 1010 1101 1111 5. Demodulate the following message (Figure 2). Remember that one symbol corresponds to one time unit (i.e., one unit on the X axis) since the frequency is 1 Hz. (4 marks) 000 amplitude Oo oo ou WNNOPNW o i 2 3 5 6 4 time (s) 7 8 Figure 2: Plot of the message signal Enter the demodulated message below. You must enter the message as a simple sequence of 0 and 1, without spaces or commas between them (for example, 0001100100)
