Binary and Gray Code Conversions

A 4-bit Binary to Gray converter has inputs B3, B2, B1, B0. The outputs are: G3=B3 G2=B3⊕B2 G1=B2⊕B1 G0=B1⊕B0 If Binary = 1010, what is the Gray code output?

In a Gray to Binary converter: B3=G3 B2=B3⊕G2 B1=B2⊕G1 B0=B1⊕G0 If Gray = 1011, what is Binary?

A Binary number 1100 goes through a Binary-to-Gray gate network: First output bit = same as MSB Remaining bits = XOR of current binary bit with previous binary bit What is the Gray output?

In a Gray-to-Binary gate network, the XOR gates are replaced with XNOR gates by mistake. If Gray = 1001, what wrong Binary output will it produce?

If Binary = 0111, using the correct Binary-to-Gray logic (MSB direct, rest XOR), what is Gray?

A BCD to Excess-3 converter adds binary 0011 using a 4-bit binary adder. If BCD = 0100, what is Excess-3?

An Excess-3 to BCD converter subtracts binary 0011 using a 4-bit adder in 2’s complement mode. If Excess-3 = 1010, what is BCD?

Two BCD digits 0001 0101 (decimal 15) go through a BCD-to-Excess-3 converter (add 3 to each digit). What is the 8-bit Excess-3 output?

Two Excess-3 digits 0111 1010 go through an Excess-3-to-BCD converter (subtract 3 from each digit). What is the 8-bit BCD output?

A BCD number is mistakenly sent through an Excess-3-to-BCD subtractor instead of an adder. If input BCD = 0100, what wrong output will be produced?
