tuned amplifier meaning in Hindi

Examples

1. Two stages of double-tuned amplifier have 80 % of the bandwidth of a single stage.
2. This response can also be achieved without transformers with two stages of a stagger-tuned amplifier.
3. The overall gain of a synchronously tuned amplifier will always be less than the theoretical maximum because of this.
4. Cascading multiple stages of double-tuned amplifiers results in a reduction of the bandwidth of the overall amplifier.
5. Like synchronous tuning, adding more stages of double-tuned amplifiers has the effect of reducing the bandwidth.
6. Stagger-tuned amplifiers can be designed to a prescribed bandwidth that is greater than the bandwidth of any single stage.
7. Designers tend to avoid the complication of mutual inductances and transformers where possible, although transformer-coupled double-tuned amplifiers are a common way of widening bandwidth without sacrificing selectivity.
8. After manufacture each tuned amplifier stage had to be " neutralized ", adjusted to cancel feedback; after this the set would not produce the parasitic oscillations which caused the objectionable noises.
9. This can be done straightforwardly for the complete filter in the case of synchronously tuned amplifiers where every stage has the same " ? " 0 but for a stagger-tuned amplifier there is no simple analytical solution to the transform.
10. This can be done straightforwardly for the complete filter in the case of synchronously tuned amplifiers where every stage has the same " ? " 0 but for a stagger-tuned amplifier there is no simple analytical solution to the transform.
