Frequency Bandwidth Calculator

Find bandwidth from center frequency and quality factor.

Calculated Output

Bandwidth (Hz) 2,000

Formula: BW = f₀ ÷ Q

Step-by-Step Breakdown

1. Values used:

2. Center frequency = 100,000 Hz

3. Quality factor = 50

5. Bandwidth = Center frequency / Quality factor = 100,000 / 50 = 2,000Hz

Did this calculator solve your problem today?

The math behind it

BW = f₀ ÷ Q. A higher Q gives a narrower, more selective bandwidth.

100 kHz with Q 50 → 2 kHz bandwidth.

Narrow or wide bandwidth?

Narrow for selectivity (tuning), wide for carrying more information.
