摘要:
A processor comprises instructions to adjust a bias of an input signal in order to decrease a duty cycle of a pulse modulated optical signal. The bias can be increased, decreased, or maintained in response to one or more measured values of the signal. In many embodiments, a gain of the signal is adjusted with the bias in order to inhibit distortion. The bias can be adjusted slowly in order to inhibit audible noise, and the gain can be adjusted faster than the bias in order to inhibit clipping of the signal. In many embodiments, one or more of the bias or the gain is adjusted in response to a value of the signal traversing a threshold amount. The value may comprise a trough of the signal traversing the threshold.
摘要(中):
处理器包括用于调整输入信号的偏置以便减小脉冲调制光信号的占空比的指令。 可以响应于信号的一个或多个测量值来增加,减少或维持偏置。 在许多实施例中,为了抑制失真,利用偏置来调整信号的增益。 为了抑制可听见的噪声,可以缓慢调节偏压,并且可以比偏置更快地调整增益,以便抑制信号的削波。 在许多实施例中,响应于穿过阈值量的信号的值来调整偏置或增益中的一个或多个。 该值可以包括穿过阈值的信号的谷。
