For a waveform displayed on a scope screen, which values indicate incorrect peak-to-peak amplitude and period?

The peak-to-peak amplitude and period of a waveform must relate to each other based on the frequency of the waveform. The peak-to-peak amplitude describes the range of voltage values from the maximum positive to the maximum negative values, while the period indicates how long it takes to complete one cycle of the waveform.

In the case of the values provided, the amplitude of 0.9 V and the period of 0.5 ms correspond to a frequency of 2 kHz. This frequency is derived from the formula frequency = 1/period. Substituting 0.5 ms (which is 0.0005 seconds) into this formula gives you a frequency of 2000 Hz, or 2 kHz.

While the period and amplitude can exist independently, the context suggests that the amplitude should make sense for a 2 kHz signal, as higher frequencies generally correlate with potentially lower amplitudes due to limitations in signal generation and measurement.

As we analyze the other answer choices, they present values of peak-to-peak voltage and period that correlate more appropriately and feasibly within expected performance levels for signal generation and measurement instrumentation at higher frequencies. Thus, option B represents a discrepancy since the combination of 0.9
