plz explain this thank you:)

1. Plot a single cycle of Sin wavefom at 440 Hz. Maximum strength should be 1000m, minimum -1000m. 1.2 800m 600m 400m 200m O -200m -400m 600m -H00m A At a sample rate of 4400, write down the values of each sample in a cycle. B. Convert all values to binary, octal, hexadecimal systems. C. Assuming each sample is going to be represented a 2 byte binary code, what is the bitrate going to be? C. Assuming each sample is going to be represented a 2 byte binary code, what is the bitrate going to be? 2. Perform a step by step multiplication of 54 and 7 in binary. Remember to write down all steps like we did in class, each step must be in binary. 3. What is the biggest number representable by the following bits of unsigned binary integers? A. 11 bits, 28 bits B. How about signed? C. How about signed with parity code? D. What if with BCD? 4. A. Show the bit configuration that represents the decimal number 42 in binay, BCD, ASCII, ASCII with even parity. B. Do it for 75
