RLC Bandwidth Calculator

Compute series RLC bandwidth BW = f₀/Q.

Input Data

Input Resonant f₀.
Hz
Input Quality Q.

Results

100Hz
BW = f₀/Q = 100.000000 Hz

At a glance:RLC Bandwidth Calculator: enter parameters to compute results; complements related calculators.

Formula

BW = f₀ / Q

higher Q → narrower bandwidth, better selectivity

How to Use

  1. Enter resonant frequency f₀.
  2. Enter quality factor Q.
  3. Get bandwidth BW.

Case Studies

f₀=1 kHz, Q=10

BW = 100 Hz.

FAQ

Vs cutoff?

f₁,₂ = f₀(1 ± 1/(2Q)); their difference is BW.
