Question

1. oscilloscopes can be used to derive frequency by measuring ________ time per cycle cycles per second (hz) volts per cycle (ez) degrees

Explanation:

Frequency is defined as the number of cycles per second. But to derive frequency using an oscilloscope, we measure the time - period (time per cycle) and then use the formula $f=\frac{1}{T}$, where $f$ is frequency and $T$ is time per cycle. Cycles per second is the definition of frequency itself and not what we measure directly on an oscilloscope. Volts per cycle and degrees are not related to measuring frequency with an oscilloscope.

Answer:

A. time per cycle
