The lower and upper cut off frequencies are also called_____________frequencies?
Correct answer: D. Half-power
- A. Sideband
- B. Resonant
- C. Half-resonant
- D. Half-power
Explanation
At each cutoff frequency, the output power falls to half its midband value, or the voltage falls to 0.707 of its maximum. Hence these are called half-power frequencies.
