Suppose the mathematical expectation of image signal is zero, the basic properties of the correlator output are given.
假定图象信号的数学期望为零，证明了相关器输出的基本性质。
2
The output of the amplifier (electrical current) is controlled by the input signal so with zero input the output current is also zero.
放大器地输出(电流)由输入信号控制，所有零输入信号，电流输出也是零。

This product is the main test project ontology counterweight and zerosignal, zero sensitivity, gradient, and outputsignal of polarity of the check, etc.
