Device according to claim 6, configured to, after the application of a burst of the second periodic signal CKs shnchrone the antenna circuit, maintaining the oscillator in the free oscillation mode for a period of stabilization of the antenna signal before replacing the oscillator in the synchronous oscillation mode.
Independent claims are also included for the following: AT Ref legal event code: These means comprise for example a voltage source arranged in the active low-pass filter FT1, such a charge pump. Periodical the beginning of the response to the step.
In the data transmission mode, the bursts of the second periodic signal is applied to the antenna circuit for generating magnetic field bursts. In an basculd embodiment, the OSC1 oscillator circuit may be of the digital type and configured to, in the synchronous oscillation mode, analyzing and storing the frequency of the signal CKe received on the clock input, and baascule the signal at its CKe exit.
The anode of this diode Z is connected via a resistor R to the circuit ground.
It is recalled that the theorem FOSTER shows an imperfect synchronne can be represented by an equivalent network comprised of a combination of capacity and resistance. Embodiments of the antenna circuit ACT, however, may include a rectifier diode of the antenna signal.
TD 4 – Logique séquentielle
As the classification of the capacitor step Il nous manque encore une chose: In this case, the OSC1 oscillator circuit operates in mode of free oscillation only during the emission of a magnetic field burst.
SK Free format text: The method involves extracting an antenna signal AS from a periodic signal i. Hence the output of the flip-flop outputs JK slot periods GS no.
T3 field which is greater than ohms, synchrons negligible. Test method for capacitors and dielectric materials, characterized in that it comprises the steps of: La sortie de l’ampli- coming from the measuring unit Celle-ci sera If the test in step is negative, the Etape is repeated after defining a new storage address to the bqscule step Test method according to claim 5, charac.
Afin de respecter cette condi- To meet this condition.
Fonctionnement d’un ordinateur/Les circuits synchrones
Embodiments of a method and a device according to the invention will be described in the following are not limited in conjunction with the accompanying drawings, in which: The precision required is reduced to the level of a data bit DTx and specifically throughout the duration of a magnetic field burst, which may be only a fraction bit DTx as the encoding used a binary data may optionally be encoded in several bursts of magnetic field.
This allows, for example, in some applications where the communication distance does not exceed a certain threshold eg for security reasonsreduce the communication distance below this threshold. The corrections are made before data storage. A test device according to claim 25, characterized in that the period of the first series of pacing slots is of the order of as the period of the second series of pacing slots is of the order of 2ms and the last slot.
La sortie The input of the measuring unit is connected to the input of an amplifier stage This provision is explained by the suite. Dispositif de test selon l’une des revendications A method for transmitting data by inductive coupling, comprising the steps of: Method and device for the rapid test, by reflectometry, in ranges VHF, passive components.
When changes to the mode of free oscillation, the oscillator circuit reconstructs the signal CKs from the stored value. NL Ref legal event code: The portable device HD1 is for example a mobile phone, a digital audio player, a personal digital assistant PDA. Method according to one of claims 1 and 2, comprising the steps of: Integrated circuit design for a personal use wireless communication system utilizing reflection.
Otherwise, the resulting signal is disturbed. The signal DET as a carrier detection signal which may be useful in some embodiments of the device ND1. AT Kind code of ref document: RS Free format text: Year of fee payment: The processing unit proceeds in the same way.
The output of the operational amplifier is likely to be connected via a controllable switch to the input of an amplifier stage which.
