TRUE or FALSE 1. A NOR gate output is LOW if any of its inputs is LOW.  2. A NOR gate and an OR gate operate in exactly the same way.  3. An OR array is programmed by blowing fuses to eliminate selected variables from the output functions. 4. A NAND gate output is LOW only if all the inputs are HIGH. 5. An AND gate

Q1. a) For the circuit shown in Figure 1, answer the following questions: D1 Y D2 Figure 1 i. Explain the working of the circuit for different input combinations along with the truth-table. ii. Modify the circuit diagram of Figure 1 to work as a NAND gate circuit. iii. Explain the working of the NAND gate circuit for different input combinations along with the truth-table.

A NAND Gate a.Goes HIGH only when all inputs are HIGH b.Goes HIGH if one or the other inputs are HIGH but not both c.Goes HIGH if any input is HIGH d.Goes HIGH only when all inputs are LOW

7. The AND operation can be produced with (a) two NAND gates (c) one NOR gate (b) three NAND gates (d) three NOR gates

Q3) a- Draw the logic diagram for a circuit that will divide the (fCLK) by 16. Use (-ve) edge triggered (J-KFF). b- Calculate the (fcLk) if the fout =(÷) MHz ----

why the XOR gate output corresponds to the sum bit, while the AND gate output corresponds to the carry bit?

Q3. Consider the following 1-bit ALU Operation - Result a. Add additional hardware to this ALU to support the NOR operation (without using a NOR gate directly): b. Write down the control values (including your new control lines) to select the NOR operation in this ALU
