5.1. In PAM encoding, the general rule is that we need to sample at twice the bandwidth. In addition, if we use n bits for each sample, we can represent 2n loudness (amplitude) levels. What transmission speed would you need if you wanted to encode and transmit, in real time and without compression, two-channel music with a bandwidth of 20 kHz and 40,000 loudness levels? 5.2. How much disk space would your require to store 30 minutes of digital music as you calculated above? 5.3. Assume that the 30 minutes of uncompressed digital music is to be transmitted over a DS-0 digital circuit at 64 Kbps. How long will it take to complete the transmission? Express you result in hours/minutes if necessary.
