摘要
讨论了电噪声测量中的直接方法,介绍了噪声测量的若干重要概念,给出了直接法校正因子。并建议,在测试标准中系统的噪声系数以1dB为宜。
This paper describes a direct method of noise measurement, introduces several important special concepts in noise test and defines two correction factors. Finally, a Standard taking 1 dB as noise figure of test system for measurement is proposed.
