The 257th bit in a large binary number is weighted as a very large decimal number.  How much more is this than the decimal value of the 256th bit? 1) The 257th bit is equal to the 256th bit. 2) the 257th bit is double the 256th bit.  3) the 257th bit is half the 256th bit. 4) the 257th bit is ten times the 256th bit.  5) the 257th bit is 256 times the 256th bit.

1. Gray code to Binary converter: Gray code is one of the codes used in digital systems. It has the advantage over binary numbers that only one bit in the code word changes when going from one number to the next. (See Table 1). Design a combinational circuit with 4 inputs and 4 outputs that converts a four- bit gray code number into an equivalent four-bit Binary number. Use Karnaugh map technique for simplification. Use LogicWorks for pre-lab demonstrations. Select the library "7400dev.clf* in the Parts Palette and then select the XOR chip 74-86. This would give you a set of 4 XOR's as shown in Fig. 1, just like the hardware chip 74-86. You could use as many as needed from these XOR gates in your design. Get back to ALL LIBRARIES and select switches for the inputs and Binary Probes as indicators of the outputs. Verify your design in the pre-Lab. During the Lab construct the circuit and verify its operations.
