Perform the multiplication of the 4-bit number 1011 (multiplicand) with 1001 (multiplier) using the optimized multiplication circuit. Demonstrate the content of product and multiplicand registers during each step. Finally show that your computation is correct by converting the multiplicand, multiplier, and product into decimal

Design a Mealy machine to detect when a value is not BCD, for example when 1111 is generated it should detect that it is not a BCD value.

You are asked to design a circuit to detect if an overflow occurs when subtracting two integers represented in two's complement: Z= X - Y. Let Sz, Sx, and Sy be the sign bit for Z, X, and Y respectively, and they are fed as input to the circuit. Let O be the output bit of the circuit, whose value is 1 if an overflow happens, and 0 if otherwise. a) Build the truth table for O as a Boolean function of Sx, Sy, and Sz. b) Write the canonical expression (sum-of-product) for the Boolean function defined in the part a. c) Implement the Boolean expression defined in part b with a circuit by using AND, OR, and NOT gates. Draw the wiring diagram.

please explain and make sure the answer is correctQuestion 2,3

Find CRC using shift register for Dataword '1010100110' and divisor pattern p is '11001' ?

Design a 2-bit modulo 8 synchronous counter in Multisim and implement the design using two 74LS112 IC JK flip flops based on this circuit. Use word generator and logic analizer as shown.

Computer Science Use two 4-bit Binary Adders to construct an 8-bit Binary Adder in VHDL Code. Also sketch a design showing how to connect two 4 bit adders together to get the 8 bit adder.

Question 3: Design a one-input, one-output serial 2's complementor. The circuit accepts a string of bits from the input and generates the 2's complement at the output. The circuit can be reset asynchronously to start and end the operation.
