A BCD code is being transmitted to a remote receiver. The bits are A3, A2, A1, and A0, with A3as the MSB. The receiver circuitry

includes a BCD error detector circuit that examines the received code to see if it is a legal BCD code (i.e., ≤1001). Design this circuit to produce a HIGH for any error condition.

<span>BCD only goes from digit 0 (0000) to digit 9 (1001), because for 10 you need two digits, so all you've got to do is make a function that produces high for numbers from 10 (1010) to 15 (1111) as follows:
A3 A2 A1 A0   F
 0    0    0    0    0
 0    0    0    1    0
 0    0    1    0    0
 ...........................
 1    0    0    0    0
 1    0    1    0    1
 1    0    1    1    1
 1    1    0    0    1
 1    1    0    1    1
 1    1    1    0    1
 1    1    1    1    1
 
Then simplify the function: F = A3*A2 + A3*A1 Finally just draw or connect the circuit using NAND</span>

Customers = 96

p = 25\% --- proportion to sign up

Required

The number of customers to sign up

This is calculated as:

n = p * Customers

So, we have:

n = 25\% * 96

n = 24

Write a program for determining if a year is a leap year. In the Gregorian calendar system you can check if it is a leaper if it
SOVA2 [1]

Answer:

def leap_year_check(year):

return if int(year) % 4 == 0 and (int(year) % 100 != 0 or int(year) % 400 == 0)

Explanation:

The function is named leap_year_check and takes in an argument which is the year which we wish to determine if it's a new year or not.

int ensures the argument is read as an integer and not a float.

The % obtains the value of the remainder after a division exercise. A remainder of 0 means number is divisible by the quotient and a remainder other wise means it is not divisible by the quotient.

If the conditions is met, that is, (the first condition is true and either the second or Third condition is true)

the function leap_year_check returns a boolean ; true and false if otherwise.

Return 1 if ptr points to an element within the specified intArray, 0 otherwise.
Paladinen [302]

Answer:

int withinArray(int * intArray, int size, int * ptr) {

      if(ptr == NULL) // if ptr == NULL return 0

            return 0;

      // if end of intArr is reached

      if(size == 0)

          return 0; // element not found

  else  

          {

            if(*(intArray+size-1) == *(ptr)) // check if (size-1)th element is equal to ptr

                   return 1; // return 1

            return withinArray(intArray, size-1,ptr); // recursively call the function with size-1 elements

         }

}

Explanation:

Above is the completion of the program.

If the computer has an encrypted drive, a ____ acquisition is done if the password or passphrase is available. a. passive b. sta
Aleonysh [2.5K]

Answer: C. Live

Explanation:

A live acquisition is where data is retrieved from a digital device directly via its normal interface such as activating a computer and initiating executables. Doing so has a certain level of risk because data is highly likely to be modified by the operating system. The process becomes significantly more common likely with less available disk space to the point of completely impractical to image.
