You wish to detect only the presence of the codes 1010, 1100, 0001, and 1011. An active- HIGH output is required to indicate their presence. Prepare the minimum decoding logic with a single output that will indicate when any one of these codes is on the inputs. For any other code, the output must be LOW. Also implement the decoding Logic using 74HC151 (8-input Data Selector/ multiplexer).

1- What does the VOH parameter of a logic IC refer to?   a) The highest permissible output voltage. b) The lowest output voltage recognized as logic 1.   c) The highest output voltage recognized as logic 1.   d) The highest output voltage recognized as logic 0.   2- Which of the following refers to the noise margin of a logic gate?   a) The difference between VIH and VOL   b) The difference between VOH and VOL   c) The difference between VOH and VIH d) The difference between VIH and VIL   3- How many 74LS00 NAND gate inputs can be driven by a 74LS00 NAND   gate outputs Refer to data sheet of 74LS00, the maximum values of IOH = 0.4 mA, IOL = 8 mA, IH = 20 μA, and IL = 0.4 mA.   4- The data sheet of a quad two-input NAND gate specifies the following parameters: IOH (max.) 0.4 mA, VOH (min.) 2.7 V, VIH (min.) =2V, VIL (max.) 0.8 V, VOL (max.) 0.4 V, IOL (max.) 8 mA, IL (max.)=0.4 mA, IIH (max.)-20µA, ICCH (max.) 1.6 mA, ICCL (max.) 4.4 mA, tpLH =pHL=15 ns and a supply voltage range of 5…

A reset input is used in IC 7493, why? a. For reset the counter       b. For setting the counter       c. For decrement of bit by 1       d. For increment of bit by 1

Using the emu8086 program, I need to solve two points and explain the difference in the solutions between them. Question: Compute the physical address for the specified each of the following instructions. The register contents and as follows: (CS)=0A00H, (DS)=0B00Н, (DI)=00BOH, (BP)=00EAH and BX-2500H. 1) Destination operand of the instruction 2) Source operand of the instruction (IP)-0000H, (SS)=0D00H, LIST=00FOH, MOV LIST [BP+DI], AX MOV CL, [BX+200H] operand in variable are (SI)=OFFOH, AX=4020H,
