Worked Example

Verified calculation

Given:

  • Frequency = 1000000
  • Filter Capacitance = 1.0E-9
  • Filter Inductance = 1.0E-6
  • Load Impedance = 50
  • Source Impedance = 50

Expected Result:

  • Insertion Loss = -6.3613303456887

Engineering Interpretation:

Under the given input conditions, the calculated result is: Insertion Loss = -6.3613303456887 dB.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

insertion loss = 20 * log(sqrt(pow(source impedance / (source impedance + load impedance), 2) + pow((2 * 3.14159265358979 * frequency * filter inductance) / (source impedance + load impedance), 2)) / sqrt(1 + pow(2 * 3.14159265358979 * frequency * filter capacitance * load impedance, 2))) / log(10)
