Question

1. oscilloscopes can be used to derive frequency by measuring

a time per cycle
b cycles per second (hz)
c volts per cycle (ez)
d degrees

Explanation:

Frequency is defined as the number of cycles per second. It is also the reciprocal of the time - per - cycle. Oscilloscopes measure the time per cycle (period) and then the frequency can be calculated as the reciprocal of the measured period. Cycles per second is the unit of frequency (Hz) but it's not what is measured directly to derive frequency. Volts per cycle and degrees are not related to deriving frequency from an oscilloscope measurement.

Answer:

A. time per cycle
