推导了受白平稳、白非平稳和色平稳噪声污染的信号的二次分布方差的精确表达式。结果表明，方差的信号相关部分与非噪声分布值密切相关。
Exact expressions for the quadratic distributions' variance of signals corrupted with white stationary, white nonstationary, and colored stationary noise are derived. It has been shown that the signal-dependent part of variance is closely related to the nonnoisy distribution values.
