can someone answer this

Regarding digital transmission of multimedia traffic, complete the following: 3.1. 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 22kHz and 1000 loudness levels? ( 10 points) Note: The sampling size, in bits, must be an integer. To minimize quantizing errors, it is customary to select a sampling rate that is twice as much as the signal bandwidth. 3.2. How much disk space would you require to store 1 minutes of digital music as you calculated above? ( 10 points) 3.3. Assume that the 1 minutes of uncompressed digital music is to be transmitted over a DS0 digital circuit at 64Kbps. How long will it take to complete the transmission? (10 points) *Don't forget units
