The exit Q thus recopies the Q’ entry. Synchronization element for converting an asynchronous pulse signal into a synchronous pulse signal.


The two chronograms of figures 40 and 41 can, in the same way that previously, being joined together in only one, as shown in the figure Moment t1 badcule the moment t2nothing changes: Ref legal event code: Indeed, a reverser is located between the two entries of validation C’ and C. Operation describes above, relating to the examined integrated circuit, is also that of any rocker of the type J. Truth table and Chronogram. One is led to the truth table of the figure b which gives the logical state of S according to the possible combinations of the logical states of the entries JK and Q.

The rocker commutates to pass to state 0. DE Date of ref document: That means that these two entries must be maintained on the level H for an operation of the rocker with the clock signal. Moreover, this state is not stable.

Rock JK Maître Slave

In the catalogs of manufacturers, the two chronograms which represent times of presetting and maintenance are gathered in only one, as shown in the figure We will see now that the effective commutation of the rocker can take place only at the time of the transition from the level L to the level H from the clock.


High-performance differential cascode voltage switch with pass gate logic elements. One speaks then about positive impulse. Thus with each active face of the clock, the exit Q rocks to take the state of and vice versa. It is not possible to envisage which of both will ignite, because that depends on the physical characteristics of the integrated circuit.

Electronic forum and Bascle. The exits of each rocker are two, Q andand they are complementary one of the other. Examination of a rocker J. Figure 4 shows the chronogram of a synchronous baecule which memorizes the data at the time of the positive transition from the clock signal.

Indeed, when the entry of order is on the level Hthe state hascule the exit follows the state of the entry. High of page Preceding page Following page.

For this handling, you will use the integrated circuit CD or type are equivalent containing two rockers J. The taking into account of the logical data can be done either on a positive transition from L to Hor on a negative transition of H with L from the entry of order.

In other words, as soon as the entry changes state, the exit also changes state. One cannot speak any more then about complementary exits. Master-slavemaitfe you will see it during this handling, is the type of most flexible rocker of the employment among all those which you will have to examine. One realizes that the exit always does not rock with each positive transition from the entry of clock.

How to make a site? Return to the synopsis. Forms maths Geometry Physics 1. Electronic forum and Infos. Circuit and method eslave switching between digital signals that have different signal rates. Pulse generating circuit in a semiconductor integrated circuit and a delay circuit therefor. Click here for the following lesson or in the synopsis envisaged to this end. A3 Designated state s: Country of ref document: This data applied in D is taken into account at the beginning of the rising face and is transferred on the exit Q to the end from this rising face.


One chose these terms to highlight the fact that the second rocker is controlled to the first as you will see it during this handling. K basculs certainly more flexible of employment than the uk D and present compared to the latter some characteristics which make it irreplaceable in certain applications. We know that the rocker D of the LATCH type makes it possible thanks to the entry of order to memorize a bit of information.

This corresponds to reality as we saw previously, the rise and fall times of escalve tension not being never null.

Examinations Rocks D in the Maître-esclave configuration and of a Rocker J.K

High of page Preceding page Following page. If this time is not respected, the data will not be taken into account by the circuit. The functions of these entries will be checked directly by the handling which will follow. Crosses X placed in boxes D and CLOCK mean that the state of these two entries does not affect any the state of the exits of the rocker.

One can also say that the data presents in D at moment t1 was transferred at exit Q to the moment t2.

Dynamic page of welcome.
