Worked Example
Verified calculation
Given:
- Measured or predicted conducted emission amplitude = 1
- Regulatory emission limit amplitude at target frequency = 0.1
Expected Result:
- Required attenuation = 20
Engineering Interpretation:
Under the given input conditions, the calculated result is: Required attenuation = 20 dB.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.
Formula / Method
required attenuation = 20 * log(measured or predicted conducted emission amplitude / regulatory emission limit amplitude at target frequency) / log(10)Formula family: formula_emc_emc_power_entry_module_required_attenuation_calculator
