1. Build and test D-type Flip-Flop using a built-in SR flip-flop.
GaryK [48]

Answer:

The attached files contain the realization of a D flip-flop from an RS flip-flop. It also contains the truth tables for both kinds of flip-flops

Explanation:

An SR flip flop is like a light switch. Set turns it 'on' and reset turns it 'off'

A D type flip-flop is a clocked flip-flop which has two stable states. A D type flip-flop operates with a delay in input by one clock cycle.

D type flip-flops are easily constructed from an SR flip-flop by simply connecting an inverter between the S and the R inputs so that the input to the inverter is connected to the S input and the output of the inverter is connected to the R input.

Alenkasestr [34]

Using the knowledge of pseudocodes it will be possible to write a code that calculates the amount of hours worked and giving warnings about it.

<h3>Writing a pseudocode we have that:</h3>

<em>while </em>

<em>if number == 0</em>

<em>break</em>

<em>hours =0 </em>

<em>for i =1 to 5 </em>

<em>hours = hours + time_out[ i ] - time_in[ i ]</em>

<em> If hours >36 : </em>

<em>print ( "Name is " ,name)</em>

<em>print ( "Name is " ,name)</em>

<em>print( "No of hours are ",hours)</em>

<em>print("Warning !!!")</em>

<em>End loop</em>

using a timer to generate a random number, develop a program that displays random numbers between 1 and 47 (or whatever) for you
mestny [16]

Answer:

Explanation:

The following code is written in Python. It creates a variable that detects the current time. Then it loops through a range of numbers and chooses the last random number after 2 seconds. Finally, it prints that number to the screen. This function can be called countless times depending on the number of state lottery numbers needed.

import random

import time

start_time = time.time()

while time.time() - start_time < 2:

   lottery_number = random.randint(0, 48)

print(lottery_number)
