What it calculates
The “Phase noise” calculator computes Phase noise in dBc from 2 parameters: l(f), dbc/hz, bandwidth, hz.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters L(f), dBc/Hz = -100, Bandwidth, Hz = 1 the result is -100 dBc (L_int = L(f) + 10log(BW)).
How to use
- Enter l(f), dbc/hz and bandwidth, hz — each field above is adjustable with a slider.
- Phase noise (dBc) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
- Copy the result or bookmark this calculator.
