Design a combinational circuit with inputs a, b, c, d and
outputs w, x, y, z. Assume that the inputs a, b, c, d represent a
4-bit signed number (2s complement). The output is also a signed
number in 2s complement which is 7 greater than the input if the
input is less than 2, and is 3 less than the input if the input is
greater than or equal to 2.

My question: what is the truth table for full-comparator??
Full question: Design a comparator circuit for binary numbers
using only NAND gates. It should take as input two numbers
represented in standard binary, X and Y, and produce two outputs, G
and L, which indicate that X is Greater than or Less than Y,
respectively. If both outputs are zero, it indicates that the
values are equal. Design a half-comparator, full-comparator, and a
full four-bit comparator. With nothing more than...

#9) You are to implement the following function
F(A,B,C,D,E,F) which outputs a 1 whenever the binary number
represented by ABCDE is ODD and 0 otherwise. A is the MSB and E is
the LSB.
Draw the function F(A,B,C,D,E,F) and show the work that led you
to that answer.
Since I am not so sadistic as to have you draw
the truth table of a 6 variable function and draw the K-map of such
a function, you should realize, as a...

Design a circuit that takes three bits, X2, X1, X0 as input and
produces one output, F. F is 0 if and only if 4<=X<=6 when X
= (X2, X1, X0) is read as an unsigned integer.

Design a 4-bit adder-subtractor circuit using the 4-bit binary
Full adders (74LS83) and any necessary additional logic gates. The
circuit has a mode input bit, M, that controls its operation.
Specifically, when M=0, the circuit becomes a 4-bit adder, and when
M=1, the circuit becomes a 4-bit subtractor that performs the
operation A plus the 2’s complement of B.Where A and B are two
4-bits binary numbers. That is,
* When M=0, we perform A+B, and we assume that
both...
