hold circuit

[′hōld ‚sər·kət]
(electronics)
A circuit in a sampled-data control system that converts the series of impulses, generated by the sampler, into a rectangular function, in order to smooth the signal to the motor or plant.

The judges of these courts, with the aid of the State judges, may hold circuits for the trial of causes in the several parts of the respective districts.
A wooden building was also constructed to serve as a temporary county clerk's office and hold circuit court proceedings, presumably located in the southeast corner of the square, although the exact location is not sure.
The hit and hold circuit design, combined with the valve chosen, must be validated for each specific application to ensure the valve will actuate under all usage conditions.
(vi) Hysteresis (2) is used to detect the maximum power point and to control the hold circuit, its output commutes to (+15 V) when the comparator (2) output reaches e3 indicating the failover of the panels operating point to the left side of the P(V) characteristic (point C in Figure 2).
Readout electronic circuit composed of charge amplifier, sample and hold circuit, buffer, differential amplifier and comparator has been realized providing the square wave output.
The integrator is followed by Sample and Hold Circuit (S/H), which is optimized for least noise contribution in terms of clock feed through (Yoon, N., 1997).
One key to great performance in a high-speed ADC is the linearity and noise of the input sample/ hold circuit, involving a capacitor, amplifier and high-speed switches.
These pulses are utilized, on one hand, for discharging the [C.sub.1] capacitor of a variable linear voltage generator which becomes thus sawtooth pulses generator with the same frequency as the input voltage, and on the other hand for commanding a S/H sample and hold circuit.
At this time the negative voltage is captured and stored by the sample and hold circuit. The stored negative voltage is used as the negative voltage reference of the latching comparator.
"Circuit City was trying to take away people's day in court," he said, adding that such mandatory agreements "make it very hard to hold Circuit City responsible for anything that it did."
Second, expensive fixturing is required to hold circuit parts in place during thermal processing.
