Consider a 4-bit successive approximation AD converter with full scale range of 5volts. Using the rounding technique, determine the 4-bit codes of the voltage values x 2.3; -1.4; 0.76; -0.4; 2.19; -0.91 volts, for the following types of converters: a. Write the code table for converting the samples of full scale range of 5 volts with the natural binary, the offset and the two's complement codes. b. Write a table for converting the values of x into the Natural binary codes, the offset and the two's complement codes.
