When a pulse wave is used to toggle an flip flop, the output frequency becomes one half the input frequency, as shown in Figure 4 Figure 4: JK Flip Flop Used as A Frequency Division ![]() Frequency Divisionįlip flops can divide the frequency of periodic waveform. They are used in digital equipments, clocks, frequency counters and computers etc. Each flip flop is triggered by the output of its proceeding flip flop. It consists of connections of flip flop without any logic gate. Figure 3 shows a simplest binary ripple counter made by flip flops. It is used to count pulses or events and it can be made by connecting a series of flip flops. CounterĪnother major application of flip flops is a digital counter. In the above four bit shift right the information from input could be transferred to output in four clock pulses. With each clock pulse information is transferred to next flip flop as shown below. Clock signal is applied simultaneously to all flip flops. Figure 2: Shift Right RegisterĮach flip flop is controlled by the output Figure 2: Shift Right Registerof the proceeding flip flop. Input data is applied to store D and shifted right. The shift register can be built using RS, JK or D flip flops.Ī four stage shift right register is shown in Figure 2. The shift register is used for multiplication and division where bit shifting is required. The shift register can be used for temporary storage of data. ![]() The data is shifted or transferred one bit at a time, when a clock pulse is applied. It may be designed to shift or transfer data either left or right. A shift register is a register which is able to shift or transfer it content within itself without changing the order of the bits. Data Transferįlip flops can also be used extensively to transfer the data. Let us suppose that flip flop one is SET(1), Flip flop 2 is RESET(0), flip flop 3 is RESET(0) and flip flop 4 is SET(1), the binary number stored in this register is (1001) 2. Any number from (0000) 2 to (1111) 2 may be stored in it simply by setting or resetting the appropriate flip flops. Figure 1: Bit Binary Registerįigure 1 shows a 4 bit register. Thus a 4 bit register consists of 4 individual flip flops, each able to store one bit of information at a time. A register is simply a data storage device for a number of bits in which each flip flop store one bit of information (0 or 1). In order to store more than one bit flip flop can be connected in series and parallel called registers. Data StorageĪ flip flop store one bit at a time in digital circuit. Flip flops are used in digital electronics some of its main applications are described below. ![]()
