Answer:

5kHz

Explanation:

There are four stages so N = 2⁴ = 16.

The frequency at nth stage is given by

\(f_n = \frac{f_{clk}}{N} = \frac{80kHz}{16} = 5kHz\)

The output frequency of the fourth stage (Q3) is 5kHz. Thus the correct option is A.

On each clock cycle, the 4-bit synchronous counter successively counts up from 0 (0000) to 15 as outputs ( 1111 ). It is also known as a 4-bit Synchronous Up Counter as result.

We required four Flip Flops to create a 4-bit counter, as indicated by the number 4 Flip Flops. The counter also has a reset pin, which enables it to enter an all-zero mode in which its output is "0."

The Q output of the previous flip-flop triggers the CLK input in the 4-bit counter above, as opposed to the Q output as in the up counter configuration, where the output of each flip-flop changes state on the rising edge.

There are four stages so N = 2⁴ = 16.

The 4-bit binary counter is 80 kHz.

In order to calculate the output frequency the  4-bit binary counter is divided by 16 which is equal to 5kHz.

Therefore, option A  is appropriate.

The program in Python is as follows:

def get_user_values():

   user_values = []

   n = int(input())

   for i in range(n+1):

       inp = int(input())

       user_values.append(inp)

   output_ints_less_than_or_equal_to_threshold(user_values,user_values[n])

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

   for i in user_values:

       if i <= upper_threshold:

           print(i,end=" ")

get_user_values()

Explanation:

This defins the get_user_values() method; it receives no parameter

def get_user_values():

This initializes user_values list

   user_values = []

This gets the number of inputs

   n = int(input())

This loop is repeated n+1 times to get all inputs and the upper threshold

   for i in range(n+1):

       inp = int(input())

       user_values.append(inp)

This passes the list and the upper threshold to the output..... list  output_ints_less_than_or_equal_to_threshold(user_values,user_values[n])

This defines the output.... list

def output_ints_less_than_or_equal_to_threshold(user_values, upper_threshold):

This iterates through the list

   for i in user_values:

If current element is less or equal to the upper threshold, the element is printed

       if i <= upper_threshold:

           print(i,end=" ")

{

 string result;

 while(integerValue > 0) {

   result += to_string(integerValue % 2);

The solution in Python is as follows:

filename = input("File: ")

fll = open(filename, "r")

for line in fll:

for i in line.split():

 print(i,end='\t')

print()

Explanation:

The complete question implies that the program reads a file and displays the file content in a structured way (tabs or spaces)

The explanation is as follows:

This gets input for the file name

filename = input("File: ")

This opens the file for read operation

fll = open(filename, "r")

This iterates through the lines of the file

for line in fll:

This iterates through each line (splitted by space)

for i in line.split():

This prints the current element followed by a tab

 print(i,end='\t')

This starts printing on another line

print()

go to your dashboard and press the number under grade to date (your percentage in the class) and it should show all your assignments that you have done and that still need to be done

a) Lowest address: 0, Highest address: (2^20) - 1. b) Lowest address: 0, Highest address: ((2^20) / 2) - 1. c) Lowest address: 0, Highest address: ((2^20) / 4) - 1.

a) If memory is byte-addressable, the lowest address would be 0 and the highest address would be (2^20) - 1.

This is because each byte in the memory requires a unique address, and since there are 2^20 bytes in total, the highest address would be one less than the total number of bytes.

b) If memory is word-addressable with a 16-bit word, each word would consist of 2 bytes.

Therefore, the lowest address would be 0 (representing the first word), and the highest address would be ((2^20) / 2) - 1.

This is because the total number of words is equal to the total number of bytes divided by 2.

Subtracting 1 gives us the highest address, as the addresses are zero-based.

c) If memory is word-addressable with a 32-bit word, each word would consist of 4 bytes.

In this case, the lowest address would still be 0 (representing the first word), and the highest address would be ((2^20) / 4) - 1.

Similar to the previous case, the total number of words is equal to the total number of bytes divided by 4.

Subtracting 1 gives us the highest address.

The screen/projector puts out data (in this case the presentation) for viewers.

In this truth table, F5 is true when there are an odd number of true inputs (x, y, and z).

The circuit for the given expression A'BC + B'CD + BC'D:

Use three AND gates:

AND1: Connect A' (A inverted), B, and C

AND2: Connect B', C, and D

AND3: Connect B, C', and D

Use an OR gate:

OR1: Connect outputs of AND1, AND2, and AND3

The output of OR1 represents the given expression: A'BC + B'CD + BC'D.

Suppose that F5 can only be true when an odd number of inputs (x, y, and z) are true in the combinational logic that produces F5. This can be demonstrated using both an XOR gate and an AND gate.

F5 = (x ⊕ y) ⊕ z

Truth table:

x | y | z | F5
