Shift registers A shift register is a circuit which uses flip-flops connected in line so that each bit which is stored at the Q output is shifted to the next flip-flop in line at each clock pulse. The clock pulses are taken to all of the flip-flops in the register, so that the action is synchronous. Any type of flip-flop whose action is suitable (edge-triggered rather than the latching or 'transparent' type) can be used, and Figure 5.1 shows typical circuits making use of edge-triggered D-types, clocked R-S types, and master-slave J-K flip-flops. To understand the operation of these circuits, recall the truth table for each flip-flop, together with the 'lockout' action which ensures that a switchover of the output occurs too late after the leading edge of the clock pulse to affect the next flip-flop, whatever type of flip-flop from the list above is used. Imagine that all the circuits of Figure 5.1 have been reset so that each Q output is set to 0, and that the data input of flip-flop 0 is at logic 1 in each case. Shift-register circuits, using three different types of flip-flop. How many licensed drivers in germany. • More than a quarter of all cars (26.4%) are compact cars (Kompaktklasse, better known in Germany as the Golf class). Total Number of Cars in Germany A few further facts on the total number of cars in Germany at the start of 2016 according to statistics: • Two-thirds (65%) of the cars are from German brands followed by 10.4% from Japan and 8.5% from France. Petrol (Benzin) engine cars have a market share of 66% and diesel 32%. • The number of electric cars registered in Germany at the start of 2016 increased by 35% to a still very modest 25,502 cars, or 0.1% market share. Note that it is the Q output of the R-S flip-flop which drives the next R input The D-type flip-flop, with a 1 at its D input, will switch over at the leading edge of the clock pulse, but the delay will ensure that its Q output does not affect the input of the next flip-flop and so alter the Q1 output after the leading edge of the clock pulse. Similarly, the R = 1, S = 0 (because of the inverter) input of the R-S type ensures that Q 0= 0, Q 0 = 1 shortly after the leading edge of the clock pulse, but with no effect on flip- flop 1. The J-K is similarly affected, with J 0 = 1, K 0 = 0 at the time of the first clock pulse, Q 0= 1, and Q 1 = 0 at the trailing edge of the clock, setting up the second J-K flip-flop for the next clock pulse.

Snes9x is pretty good as well if you prefer windows stuff. Electronics Tutorial about the Shift Register used for Storing Data Bits including the Universal Shift Register and the Serial and Parallel Shift Register. The truth table and following waveforms show the propagation of the logic “1” through the register from left to right as follows. Then to summarise a little about Shift. Whatever type of flip-flop circuit is used, therefore, the action of the first clock pulse on the first flip-flop has been to switch the output from the original setting of logic 0 to logic 1, the voltage of the data input. At this first clock pulse, each of the other flip-flops in the chain has had a data input equal to zero from the previous stage (R =1, S= 0 for the R-S type) so that the first clock pulse leaves each flip-flop except the first unchanged with zero output. See Figure 5.2. At the second clock pulse, however, with the data input to the first flip-flop still at logic 1, the data input to each of the second flip-flops is also 1 (R = 0, S= 1 for the R-S type). At the second clock pulse, therefore, the output of flip-flop 1 will be unchanged, but the output of flip-flop 2 will switch over to logic 1. ![]() The other flip-flops which follow will be unaffected because at the leading edge of the clock pulse they have both had zero input. At the third clock pulse, assuming that the input is still held at logic 1, the third flip-flop of each chain will switch over, leaving the fourth at logic 0. The fourth flip-flop will, in turn, switch over on the fourth clock pulse. The shift action of the register illustrated Shift registers form a very important class of components in all types of digital circuits. Because the flip-flop output is changed only by a clock pulse after the input has been changed, the removal of clock pulses, leaving only the supply voltage present, leaves the output of the flip-flop unchanged for as long as these conditions are maintained. Each flip-flop can therefore be made to store a binary digit (or bit) for as long as the power is applied and the clock pulses are gated out. A set of binary digits can be stored in a register which has one flip-flop for each digit. We can expect, then, to find shift registers extensively used wherever there is any reason to store bits from one operation to another, and several typical register applications are detailed in this chapter and also in Chapter 7, which deals with microprocessors. Before we look at a selection of shift-register circuits, we nee to note that there are four basic types of register. The type shown in Figure 5.1 is a Serial-In-Serial-Out (SISO) type. The logic voltage at the input is fed into the shift register at each clock pulse, and can change in the time between clock pulses. After a number of clock pulses equal to the number of flip-flops in the register, the same bit is available at the output. A SISO register used in this way can act as a time delay the bits at the output are delayed by several clock pulses (equal to the number of flip-flops) compared to the bits at the input. A PIPO register Another basic type of shift register is the Parallel-In-Parallel Out (PIPO) type ( Figure 5.3).
