5. In an audio CD, the audio voltage is typically sampled about 44,000 times per second, and the value of each sample is recorded on the CD surface as a binary number. In other words, each recorded binary number represents a single voltage point on the audio signal waveform. (8 points) a. If the binary numbers are six bits in length, how many different voltage values can be represented by a single binary number? Repeat for eight bits and ten bits. b. If ten-bit numbers are used, how many bits will be recorded on the CD in one second. c. If a CD can typically store 5 billion bits, how many seconds of audio can be recorded when ten-bit numbers are used? Represent the statement "X-25 Y in ASCII code (excluding quotes). Attach an odd parity bit. (3 points) 7. Show the result of each of the following calculations in binary using the two's complement method. Assume 8 BITS. (8 points) a. 99-36 b. -54-45
