And for the frame beam end bending moment amplitude modulation factor seems embodiment its value in practice projects.
框架梁端的弯矩调幅系数的合理取值的价值在实际工程中似乎更能体现出来。
The amplitude modulated wave with any modulation factor is discussed in this paper. Its expression, spectrum and formula of the modulation factor, modulation efficiency, SNR gain are given.
