Code Converters and Multiplexers Questions

• A microcontroller differs from a microprocessor in that it has several ________ ports and ________ built into its architecture, making it better suited for ________ applications.
• The primary use for Gray code is:
• How many inputs are required for a 1-of-10 BCD decoder?
• What is the function of an enable input on a multiplexer chip?
• Why is a demultiplexer called a data distributor?
• A binary code that progresses such that only one bit changes between two successive codes is:
• A truth table with output columns numbered 0–15 may be for which type of decoder IC?
• In a Gray code, each number is 3 greater than the binary representation of that number.
• How many inputs will a decimal-to-BCD encoder have?
• How many inputs are required for a 1-of-16 decoder?
• How many exclusive-NOR gates would be required for an 8-bit comparator circuit?
• The inputs/outputs of an analog multiplexer/demultiplexer are:
• One way to convert BCD to binary using the hardware approach is:
• If two inputs are active on a priority encoder, which will be coded on the output?
• A BCD decoder will have how many rows in its truth table?
• A principle regarding most IC decoders is that when the correct input is present, the related output will switch:
• One multiplexer can take the place of:
• For the following conditions on a 7485 magnitude comparator, what will be the state of each of the three outputs? A0 = 0 B0 = 1 IA < B = 0 A1 = 1 B1 = 0 IA = B = 1 A2 = 1 B2 = 0 IA > B = 0 A3 = 0 B3 = 0
• The expansion inputs to a comparator are used for expansion to a(n):
• Why is the Gray code more practical to use when coding the position of a rotating shaft?
