A PCM communication system has 4 codewords: 00, 01, 10, 11; the first two are for positive voltages, the second two are for negative voltages. These are arranged in the way we have become used to seeing them arranged: the larger the binary number the larger the *magnitude* of the signal. The gap between codewords is 1 volt. No codeword gap straddles the 0 volts value. Sketch this coding scheme and determine which codeword pattern represents the following samples: 0.1v, -0.5v, 1.5v, -0.4v. Is it: Select one: a. 00 00 01 00 O b. 00 10 01 10 O c. 11 00 01 00 O d. 01 01 01 00
