Correctly answer all exercise
observation of waveforms, its use as a device for measurement of frequency
has the inherent limitation of approximately 3% accuracy.

Electronic counters are considered to be the most accurate,
convenient, and flexible of all the available instruments for making
They cover a wide variety of
features allowing measurement of frequencies from dc to 40 GHz and time
intervals from 10 nanoseconds to more than 100 days.
An electronic counter is used for the comparison of an unknown
frequency or time interval with a known frequency or known time interval.
The counter's logic is designed to present this information in an easy to
read numerical display. The accuracy of the measurement depends, to a great
extent, on the stability of the known frequency. This known
