Understanding Q Factor and Bandwidth
The quality factor (Q) of a tuned amplifier is a measure of its selectivity and bandwidth. It defines how well the circuit can select a narrow frequency range. A higher Q indicates a narrower bandwidth, while a lower Q indicates a wider bandwidth.

Impact of Doubling Q
When the Q of a single stage single tuned amplifier is doubled, the effect on bandwidth can be analyzed using the relationship between Q and bandwidth (BW):
  • Formula: BW = f0 / Q
  • Where:
    • BW = Bandwidth
    • f0 = Center frequency
    • Q = Quality factor





Calculating Bandwidth Change
1. **Initial Conditions:**
- Let Q1 = initial Q
- BW1 = f0 / Q1
2. **After Doubling Q:**
- Q2 = 2 * Q1
- BW2 = f0 / Q2 = f0 / (2 * Q1) = BW1 / 2
This shows that when the Q factor is doubled, the bandwidth becomes half of its original value.

Conclusion
Thus, with a doubling of the Q factor in a single stage single tuned amplifier, the bandwidth does indeed become half, which confirms that the correct answer to the question is option 'B'.
