摘要： Provided is a current detection circuit that can detect current in a wide dynamic range, with high precision, and with good step response. Voltage that is generated between both ends of a resistor connected between a high-voltage power supply and a load is amplified by amplifiers and compared, by comparators, to the voltage of a saw-tooth wave signal; the lengths of signals indicating the comparison results from the comparators during an inclined period in which the voltage of the saw-tooth wave signal linearly and gradually increases or decreases and the length of the inclined period are detected; and the current flowing to the resistor is detected on the basis of the ratio between the detected lengths.

摘要： A waveform analyzing section analyzes the waveform of a detector signal pulse. A calculation section calculates a count rate from the addition-subtraction accumulated value of an up-down counter, and detects noise intrusion, based on the output from the waveform analyzing section. When noise intrusion has been detected, the addition-subtraction accumulated value for the present calculation cycle is replaced with the value for the previous calculation cycle. When the noise intrusion has stopped, the addition-subtraction accumulated value of the up-down counter is set at the value for a calculation cycle just before the noise intrusion, by an accumulated value setting circuit.

A presetable up/down counter provides an output representative of the rate of change of the parameter value to be displayed, and a logic circuit arrangement is operable, subject to the up/down counter output, for allowing application of different frequency data update pulses to the data update strobe terminal of the meter so that the meter automatically switches from a slow to a fast data update rate when the rate of change in the parameter exceeds a predetermined limit. Also disclosed herein is a tachometer which can be used with different engines, the tachometer including a digital read-out meter circuit wherein the frequency multiplier arrangement includes selective switching means for multiplying "X" number of pulses per engine revolution by different numbers so that engine rpm of different engines can be counted and read out directly by the digital meter.

摘要： A device for measuring spatial displacement comprises two similar elementary capacitors of a differential capacitor and which share a common movable armature and the two capacitors are used to produce respective pulses whose lengths are compared to produce a third pulse whose length is proportional to the displacement of the armature. In a preferred embodiment, the capacitors are switched in alternation into an oscillating circuit and serve to determine the frequency of oscillation thereof and the time taken for a fixed number of oscillations to be produced with each capacitor switched in is measured to produce the first and second pulses. An adder/subtractor counter is provided which provides a fourth pulse whose length is equal to twice that of the first pulse and the fourth pulse is compared with a pulse whose length equals the sum of the first and second pulses to produce the third pulse.

摘要： In a DVOM of the dual slope type, an unknown resistance or conductance to be measured is connected to a reference signal source to generate a voltage or current which is measured by the DVOM. However, if the input impedance of the DVOM is not extremely high, it loads the unknown resistance or conductance, and renders the relationship between the value of the unknown resistance or conductance and the actual voltage or current measured by the DVOM non-linear. In order to correct for this, a proportion of this actual voltage or current is algebraically summed with the reference signal used in the DVOM for generating the second slope of its dual slope operation, the proportion being selected in dependence on the input impedance of the DVOM (which can thus now take any convenient value) to linearize the relationship between the value of the unknown resistance or conductance and the output signal of the DVOM.
