Explanation: A comparator is used to compare the output of the digital to analog converter in a successive approximation type DVM. As a result the comparator provides high or low signals.

Explanation: The linear ramp technique essentially consists of a linear ramp. It is either positive or negative going. Range of the linear ramp varies from –12 V to +12 V. Base range varies from –10 V to +10 V.

Explanation: Initiation of the measurement cycles is taken care of by the sample rate multivibrator. This vibrator oscillates at the rate of 1000 cycles per second. It is adjusted by a front panel control.

Explanation: Momentum of the electrons gives the intensity or brightness of the light emitted from the fluorescent screen due to electron bombardment. It is given as the product of the no of electrons and their speed.

Explanation: In a Dual Trace Oscilloscope, the alternate mode of operation enables to maintain the correct phase relationship between the signals from the channels A and B.

Explanation: In Sequential repetitive sampling, pretrigger information cannot be captured. And the pretrigger view is lost. It can be used only in microwave digital oscilloscope as a result.

Explanation: The typical functions of auxiliary equipments include linearization and limit compression for the input signals. Individual instruments or a digital computer is used to perform these functions.

Explanation: A digital panel meter usually abbreviated as DPM is the best example of a single channel data acquisition system.

Explanation: The successive approximation technique is most widely used in a single channel data acquisition system. This is due to the fact that it has a high value of resolution and high speed.

Explanation: Process control is mainly used in order to control the physical parameters including temperature, pressure, flow rate, force, etc.
