This table helps you verify the calculator with realistic molecular switching measurements.
Primary Switching Ratio: Switching Ratio = On-State Value / Off-State Value
Ratio in dB: Ratio dB = 10 × log10(On-State / Off-State)
Log Ratio: Log Ratio = log10(On-State / Off-State)
Absolute Switching Window: On-State − Off-State
Percent Gain: ((On-State − Off-State) / Off-State) × 100
Contrast Ratio: (On-State − Off-State) / (On-State + Off-State)
Noise Adjusted Ratio: (On-State − Noise Floor) / (Off-State − Noise Floor)
Retained On-State: On-State × (Retention / 100)
Retained Ratio: Retained On-State / Off-State
Molecular switches change between two measurable states. One state is high output. The other is low output. The switching ratio shows how clearly those states separate. A larger ratio usually means easier signal discrimination. That matters in sensing, memory design, and nanoelectronic studies.
This calculator focuses on the on-state and off-state response. Those values can represent current, conductance, intensity, or another comparable signal. The primary output is the switching ratio. It also reports dB form, log ratio, contrast ratio, and percent gain. These extra metrics help compare devices across different experiments.
Real measurements contain background noise. A noise floor can distort weak off-state readings. The noise-adjusted ratio gives a cleaner view when the baseline is known. Retention also matters. Some molecular switches lose performance after repeated exposure, bias stress, or storage. Retained ratio estimates post-test separation after that decay.
A ratio near 1 suggests weak switching contrast. A larger ratio indicates stronger state control. The dB output is useful when reviewing orders of magnitude. Contrast ratio helps normalize results between negative and positive windows. Absolute switching window is helpful when you care about raw signal spread instead of normalized behavior.
Use matched units for on-state and off-state values. Keep temperature, voltage, and environment consistent across samples. Record baseline noise from the same instrument settings. Compare ratios with retention when long-term stability matters. Exporting results to CSV or PDF also makes lab documentation cleaner and faster for later analysis.
It is the ratio between the measured on-state output and the off-state output. It shows how strongly a molecular device separates its two switching states.
Use any consistent unit for both states. Current, conductance, intensity, or resistance-derived signals can work. The key rule is that both values must use the same basis.
The ratio divides by the off-state value. A zero or negative denominator makes the calculation invalid or physically misleading for this simple comparison model.
The dB output expresses the ratio on a logarithmic scale. It helps compare switching strength when values span several orders of magnitude.
Use it when your instrument has measurable baseline signal. It helps estimate a noise-adjusted ratio and can improve interpretation for weak off-state values.
Retention estimates how much of the on-state remains after stress or aging. The calculator uses it to show a retained on-state value and retained ratio.
Usually yes for state separation, but not always alone. Stability, repeatability, operating voltage, response speed, and noise tolerance also matter in device evaluation.
Yes. After calculation, you can download a CSV summary or generate a PDF report directly from the result section.
