Technician A says a that a voltmeter can be used to monitor the output signal of an optical sensor. Technician B says that optic
al sensors should be tested with an oscilloscope because of the sensor's speed. Which technician is correct? A. Technician A only
B. Technician B only
C. Both technicians A and B
D. Neither technician A nor B
An oscilloscope can be used to check the output signal of an optical sensor. The oscilloscope has the functioning of viewing the results in the form of waveform and its time scale settings can be altered to meet the requirements of the results.
A voltmeter cannot be <u>directly</u> used to monitor the output signal of an optical sensor. But a <u>digital multi-meter</u> can be used to check an optical sensor if the digital multi-meter is set on AC - Volt reading mode.
Frame of reference, in simplest terms, describes the state of motion of the observer. The frame of reference may also be described by using a set of coordinates, time and motion. We formulate all our equations and solve them using the frame of reference.
