Equation for bandwidth - correct units (cycles/sec or radians/sec)?

[dculp1]

If the bandwidth for an RLC series circuit is defined as f2 - f1, then what are the correct units for the frequencies?

(about half way down) uses Hz.
-

https://en.wikiversity.org/wiki/RLC_circuit#Bandwidth

uses radians/sec.

Is there a definitive reference for this?

Thanks,
Don C.

It's irrelevant. Since the bandwidth of a circuit is based upon the point at which the amplitude has dropped to 70.7% of the max, you can call them whatever you want.

It's more convenient to put them in terms of Hz or radians (depending upon if you're dealing with straight frequency ranges, portions of the unit circle, etc.), but nothing says you have to... but your readers should understand what you mean, and keeping a standard helps.

Classically, in analog linear circuits, capacitive reactance is given by j*ω*C, where ω is in radians. and ω = 2πf

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!
