You are an engineer at a company planning the design and manufacture of a digital answering machine. Given a sampling rate of 12KHz and a quantization of 8 bits, how much memory (MBytes) is required to store 20 minutes of conversation? What size memory chip (in MBytes) is appropriate? (Recall that memory chip sizes are available in powers of 2. For example, 2KB, 4KB, 8KB, .. 2MB, 4MB, 8MB, 16MB, 32MB, 2GB, 4GB, 8GB, 16GB, etc.) Must show all steps of the calculation. If your manager says the overall total cost for the memory chips is too high, what would you recommend to reduce costs (or needed capacity) of memory chips? What questions would you ask
