The Learn the Analysis of a D-Latch Flip-Flop with Deeds
No full textA D Flip Flop (also known as a D Latch or a ‘data’ or ‘delay’ flip-flop) is a type of flip flop that tracks the input, making transitions with match those of the input D. The D stands for ‘data’; this flip-flop stores the value that is on the data line. It can be thought of as a basic memory cell. In an active high SR Flip Flop is when S (Set) and R (Reset) both are 0, there will be no change in the output of the latch, and when both S and R are 1 the output of the latch is totally unpredictable. In an active low SR Flip Flop when S and R both are 1, there will be no change in the output of the latch, and when both S and R are 0 the output of the latch is totally unpredictable. So if both inputs of the flip-flop are the same there will either be a No Change or Invalid output condition. If we avoid these conditions of inputs, there will be either SET or RESET conditions.
There are many applications, where only SET and RESET conditions of the latch are required. In these applications, we can use inputs (S and R) which are always the complement of each other.
This can be designed by a single input (S) to the latch and the R input achieved by inverting this S. This single input is called data input and it is labeled with D.
This is why this type of single input Flip flop is known as a D-Flip Flop or D Latch. The basic logical representation (i.e. circuit diagram) of a D-flip flop is shown on Rajah 1
Perancangan Aplikasi Mobile Warteg
No full textMakanan Warteg merupakan makananan yang mayoritas dihidangkan pada rumah-rumah keluarga di Indonesia. Dengan adanya aplikasi mobile pemesananan makanan warteg ini, maka akan memudahkan pengguna dan penyedia jasa warteg untuk melakukan pemesanan dan mengelola menu makanannya. Terlebih dengan adanya pandemi Covid-19, maka aktivitas masyarakat dibatasi pada cakupan dan batas tertentu, padahal industri warteg termasuk usaha kecil dan menengah yang perlu tetap berjalan. Sehingga melalui pemanfaatan aplikasi mobile smartphone ini disamping turut memasarkan masakan tradisional nusantara secara online juga membantu peningkatan perekonomian usaha kuliner kecil dan menengah, karena aplikasi tersebut tidak terhubung ke pihak ketiga namun langsung berhubungan antara penjual dan pembeli sehingga dari segi keuntungan harganya dapat lebih menguntungkan kedua belah pihak. Konsumen dapat melakukan pemesanan makanan warteg secara online, kemudian melakukan transaksi pembayaran sebagaimana dijelaskan di dalam aplikasi, kemudian penjual/pemilik warung akan mendapatkan notifikasi ke email dan menyiapkan pengiriman makanannya ke tujuan konsumen. Perancangan aplikais menggunakan model rapid application development melalui platform ibuildapp, yang menekankan pada kecepatan perancangan prototype. Dari hasil instalasi file APK aplikasi dan testing, semua fungsi utama pemesanan dan notifikasi ke penjual berfungsi dengan baik, namun demikian perancanga aplikasi ini masih terdapat keterbatasan, dimana menu pembayaran masih terpisah dari aplikasi karena keterbatasan resources yang dimiliki penulis, untuk itu ke depan kiranya bisa juga dikembangkan aplikasi mobile pemesanan makanan yang dapat langsung terhubung dengan fitur pembayaran

Get PDFClassification of Sequential Logic
As standard logic gates are the building blocks of combinational circuits, bistable latches and flip-flops are the basic building blocks of sequential logic circuits. Sequential logic circuits can be constructed to produce either simple edge-triggered flip-flops or more complex sequential circuits such as storage registers, shift registers, memory devices or counters. Either way sequential logic circuits can be divided into the following three main categories:
1. Event Driven– asynchronous circuits that change state immediately when enabled.
2. Clock Driven– synchronous circuits that are synchronised to a specific clock signal.
3. Pulse Driven– which is a combination of the two that responds to triggering pulses.
SR Flip-Flop
The SR flip-flop, also known as a SR Latch, can be considered as one of the most basic sequential logic circuit possible. This simple flip-flop is basically a one-bit memory bistable device that has two inputs, one which will “SET” the device (meaning the output = “1”), and is labelled S and one which will “RESET” the device (meaning the output = “0”), labelled R.
Then the SR description stands for “Set-Reset”. The reset input resets the flip-flop back to its original state with an output Q that will be either at a logic level “1” or logic “0” depending upon this set/reset condition.
A basic NAND gate SR flip-flop circuit provides feedback from both of its outputs back to its opposing inputs and is commonly used in memory circuits to store a single data bit. Then the SR flip-flop actually has three inputs, Set, Reset and its current output Q relating to it’s current state or history.
The term “Flip-flop” relates to the actual operation of the device, as it can be “flipped” into one logic Set state or “flopped” back into the opposing logic Reset state
