SEQUENTIAL CIRCUIT
sequential circuits tattoos with output levels at any instant of time are depend not only on the level results at the time but also on the video in good condition circuit switching have memory sequential circuit army of combinational circuit and example flip flops
FLIP FLOP
a v block is a bistable electronic circuit that has to stable states that is one output is ideal for that can be generated as a memory device that is used for storing one binary bit it is made up of logic logic GATE by itself as not storage capacity several logic kids can be converted together in a vehicle information
TYPES OF FLIP FLOPS
rs flip flop
d flip flop
JK flip flop
t v flip shop
CLOCK SIGNAL
block is a rectangular pulse train for a square wave as shown in the figure in synchronous system the control input determine what state the output will go to the clock input determined when the output will change state output can change States only when the clock makes a transmission also called as are pointed out of the figure
when the clock changes from 0 to 1 this is called the positive going transmission that changes is said to be positive
when the clock goes from 120 this is a negative going transmission circuit that changes states are the time is said to be negative edge triggered
most digital system changes state in synchronous system clock it change of state will occurs as the clock transmission from low to high or as it transfers from high to low this is called as asynchronous operation tuta easier to design for troubleshoot because the circle prove that can change only at specific instant of time
in some digital circuit change of state occurs regardless of a system clock for instance the operation of a push button reset by human operation maitri result in a assistant change of state that is not in synchronous with the clock this is called as asynchronous operation it is more difficult to design and troubleshoot and assistance system
CLOCK FLIP FLOP
locket fabricpath design to change state on of an application of the clock that is labelled clock
flip flop maybe level trigger trigger trigger respond to changes in the input when the clock is height no normal at the clock input terminals indicates the high level trigger
darji ticket discount only with output present at the transmission of the clock pulse triggering is also called dynamic ram
shikhar 2.3 with small trigger on the clock input to indicate that it is activated only when the positive going to the other part of the input have an effect on the talking foot
flip flop symbol as well as it written on the clock circuit signifies that the clock input is activated only when the negative transmission occurs on the part of the input pulse will have an effect on the block
the control inputs of controlled flip flop will have no effect on TV until active clock transmission occurs in other words their effect is synchronised with signal applied to clock for this reason they are called control input the control input determines what state of output will go to the clock input depends when we change States
LIGHT
IS INTERNAL SYSTEM OUTPUT OF LOGIC CIRCUIT CAN BE CHANGED STATE WHEN THE CONTROL INPUT CHANGES THERE IS NO CLOCK THE TERM LATCH DEFINITELY
as temporary buffer memory is is more difficult to design and troubleshoot as asynchronous system
GATED LATCH
gated latches are level triggered they respond to the input only when the enable or getting signal is high in the absence of enable are getting signal the light does not respond to the changes in the input
ACTIVE HIGH INPUT LATCH
active I means that the set and reset input are normally resetting in the lost state and one of them will be cultured hi whenever we want to change the light output
ACTIVE LOW INPUT LIGHT
active low means that the set or reset input are normally resetting in the high state and one of them will be pulsatilla whenever we want to change the light output
ROCKET RS FLIP FLOP
rs flip flop are designed to change state of an application of a clock that is labelled circuit 2.2 shows the logical circuit symbol to table logic circuit and timing diagram for rs flip flop
condition is logically with the basic definition of flip flop that required to be the complement of you that is unpredictable undefined or ambitious the flip flop is said to be in the forbidden state this is shown in the first row of the truth table
figure 2.5 shows the timing diagram for the clock direct before clock pulse set input is is made 0 and reset input are is made 11 o'clock girls one occurs output queue is reset q = 0 irrespective of its previous state club to send the input in the old Mod therefore the output does not change before clock pulse 3 occurs as is made one and r is made 01 clock pulse 3 occurs output queue is set clock pulse fore sense the input in the hold more and therefore the output is not change
ROCKET JK FLIP FLOP
setting when an rs flip flop forces both you and Cuba to the same logic level this is an illegal condition and it is not possible to predict the final state of the j-k flip-flop accounts officer input it is very versatile and also the most widely used the j and k destruction for the control input have a significant the function of the j-k flip-flop is identical to that of the rs flip flop expect that is have no invited state like the rs flip flop
