Signal Coding Lab

In this lab, we will develop the digital signal code for a very basic, notional codec. A specialized application has been developed which needs to quantize analog signals varying between -3.5 volts and +3.5 volts (see figure). The proper sampling frequency has been determined, and the sensitivity requires that each sample be within 0.5 volts of the true analog signal. Your job is to provide a digital (binary) code, using the minimum number of bits necessary, to represent each voltage, in 0.5-volt increments, from -3.5 volts to 3.5 volts.

When the blank lines on the left of the figure are filled in with your digital code, the graph will be similar to (but not the same as) graphs in figure 3-20 of the text.

Turn-in Requirements : To complete the assignment, upload a Word (.docx) or Adobe (.pdf) file with answers to the 2 questions below, followed by a table or list indicating your digital code representation for each voltage level as your submission to the M03 Lab assignment in Blackboard.

1. (5 pts) How many different voltage levels must be represented?

2. (10 pts) How many bits are needed to represent at least this many levels? What about 17 levels? Show your work.

3. (15 pts) Fill in the below table
