| Abstract: | The necessity of quickening response and widening frequency band in the design of high-fidelity power amplifier is elaborated. The relationship among frequency response, power bandwidth and the transforming rate are pointed out. The approaches to widening bandwidth and enhancing transforming rate are put forward. Taking account of the experimental results and the evaluation of subjective sound listening, it is confirmed that quick response and wide frequency band of amplifier can improve the sound quality. |
