Another application for Flip-Flops is division frequency devices.
From J-K flip-flop can be used to build a frequency divider by taking the output of one cell to the clock input of the next. The J and K inputs of each flip-flop are set to 1 to produce a toggle at each cycle of the clock input. For each two toggles of the first cell, a toggle is produced in the second cell, so its output is at half the frequency of the first.
Specifically, the combination J = 1, K = 0 is a command to set the flip-flop; the combination J = 0, K = 1 is a command to reset the flip-flop; and the combination J = K = 1 is a command to toggle the flip-flop, i.e., change its output to the logical complement of its current value.
Both PS and CLR HIGH, a negative-going CLK, and J and K at 0, or LOW. In this condition the FF holds the previous condition of the output. In this case the FF is reset. If the circuit were set when these inputs occurred, it would remain set.
In the following experiment we build a binary counter using J-K flip-flops by taking the output of one cell to the clock input of the next. The J, K inputs of each flip-flop are set to 1 to get toggle at each clock pulse. For each two toggles of the first cell, a toggle is produced in the second cell, and so on. This produces a binary counter device. The count can be in forward or backward direction making a modification like shown below.
The BCD counter showed above can be build using several binary counters but with a small modification, by terminating the count when the count reaches decimal 9 or binary 1001. Since the next toggle would set the two most significant bits a NAND gates tied from those two outputs to the asynchronous clear line will start the count over after 9.
A 2-bit binary counter using two J-K flip-flops is done by taking the output Q of one J-K flip-flop to the clock input of the next. The J, K inputs of each flip-flop are set to 1 to ...

There were two sectors in the development of the Korean electronics: labour-intensive consumer products and integrated circuit (IC) assembly. One of the top players in the manufacturing and exporting of electronics products in Korea was Samsung (Steinberg, 2010).
In this paper, I will discuss a public figure, Steve Jobs, who made his name in the field of digital electronics. Steve Jobs became the leader of the world of digital electronics through his vision and unending struggle. He was the person who had the ability to predict the future prospect of the computer business, and that was the major reason behind his success in the world of digital electronics.
IP3 Overview of the Company LG Electronics, established in 1997, is a brand renowned for providing Home Entertainment appliances to millions of customers. Its main line of products consists of Plasma TVs, Audio Home Theatres, Refrigerators, Washing Machines, Air Conditioners and Vacuum Cleaners.
It initiated the concept of 'Big Box’ (Grasser and Meller 2009, p.6). This one-stop-outlet of innovation and benchmark success in retail distinction, customer care, and convenience was expected to reach more than 40 stores come the end of year 2012. As a full service vertically integrated electronic company, Emax provides the widest range of more than100, 000 goods across 20 and more categories from three hundred brands in the sector of electronics.
A digital system is a combination of various devices which are designed to manipulate the logical information or the physical quantities which have been represented in digital form. This signifies that the quantities can only take discrete values. The digital devices are mostly electronic.
It is possible that a new non-electronic technology might be discovered and makes the electronic stereo hafiz-system as dead and archaic as is the Edwardian today.
In the ever developing technology of today, electronics is essential in many areas such as communications, automatic control, automation, computing and instrumentation.
Logic employed on computers are binary by nature as well. One may find it convenient to interpret the two discrete values as two different integers, or analogously, as the two truth values namely “true” or “false”. This concept
