However, inside a circuit simulator (or even when solving a circuit on paper!), we have to pick one node to be our reference in order to calculate voltages at other nodes.Ī node in an electrical circuit is a place where two or more circuit elements meet. In real life, ungrounded battery-operated circuits work just fine, because to the circuit, only relative voltages matter. The concept of a ground in a circuit simulator is similar but not identical to the concept of an electrical ground in the physical world. This means that every circuit has to have at least one GND element, or the circuit will not simulate. ![]() CircuitLab is not compatible with browser zoom, and currently has no way to detect this condition.)Įvery voltage in CircuitLab is calculated relative to the ground ( GND) node, which is by definition at 0 volts.

Holding down the Ctrl key while clicking and dragging on the grid will allow you to pan the viewport. You can switch to Simulate Mode by clicking the "Simulate" button along the bottom toolbar.Ĭlick a component in the Build Box to select it, and then click somewhere on the grid to insert into your circuit.ĭouble-click any component in your circuit to bring up the corresponding parameter editor. F0c/N, F0c étant une fréquence de consigne pour le résonateur mécanique et N un nombre entier positif.Le circuit de régulation est agencé pour pouvoir détecter une dérive temporelle, négative ou positive, dans l'oscillation du résonateur mécanique et pour générer, dans une période de correction, en association avec le dispositif de freinage, lorsque la dérive temporelle correspond à au moins un certain retard, une série d'impulsions de freinage qui sont appliquées au résonateur mécanique à une fréquence FSUPdans une plage de valeurs donnée et de préférence supérieure à une fréquence FZ(N) = 2 La pièce d'horlogerie (2) est munie d'un mouvement mécanique (4) qui comprend un résonateur mécanique (14), un capteur (24) détectant les oscillations du résonateur mécanique, et un dispositif de freinage (26) agencé pour générer des impulsions de freinage en réponse à un signal de commande (SF) fourni par un circuit de régulation (22) associé à un oscillateur auxiliaire. The control circuit is arranged to be capable of detecting negative or positive temporal drift in the oscillation of the mechanical resonator and to generate, in a correction period, in association with the braking device, when the temporal drift corresponds to at least a certain loss, a series of braking pulses which are applied to the mechanical resonator at a frequency F, in a given range of values which is preferably higher than a frequency F(N)=2*F0c/N, F0c being a set point frequency for the mechanical resonator and N a positive integer number.SELECTED DRAWING: Figure 1 Abstract (fr) To provide a timepiece assembly comprising a mechanical oscillator associated with an electronic device for controlling its mean frequency.SOLUTION: A timer (2)is provided with a mechanical movement (4), which includes a mechanical resonator (14), a sensor (24) detecting oscillation of the mechanical resonator, and a braking device (26) arranged to generate a braking pulse in response to a control signal (S) provided by a control circuit (22) associated with an auxiliary oscillator.
