摘要： Methods, circuits, and systems for determining the presence of a chopped input signal are disclosed. A digital signal generator can produce multiple digital signals when an alternating current (AC) signal input reaches multiple threshold voltages. The times at which the threshold voltages are reached can be determined by looking at the times at which the digital signals go high and low. The differences between the times at which the digital signals go high and low are used to determine if the AC signal input is a leading or trailing edge chopped signal. The AC input signal is a leading edge chopped signal when the difference between the times at which the digital signals go high is less than a predetermined time threshold, and is a trailing edge chopped signal when the difference between the times at which the digital signals go low is less than a predetermined time threshold.
摘要翻译：公开了用于确定斩波输入信号的存在的方法，电路和系统。当交流（AC）信号输入达到多个阈值电压时，数字信号发生器可以产生多个数字信号。达到阈值电压的时间可以通过查看数字信号变为高电平和低电平的时间来确定。使用数字信号变为高电平和低电平的时间之间的差异来确定AC信号输入是前导或后沿斩波信号。当数字信号变高的时间之间的差小于预定时间阈值时，AC输入信号是前沿斩波信号，并且当数字信号到达时间之间的差异时是后沿斩波信号低于预定时间阈值。

摘要： Provided are a detector for a multi-level modulated signal and a detection method using the same, and an iterative receiver for a multi-level modulated signal and an iteratively receiving method using the same. The detector includes: a channel estimator estimating a channel response of each of a plurality of bits included in at least one received signal based on multi-level modulation; a hard decision unit, for each bit, selecting at least one of a plurality of bits remaining by excluding the bit and performing a hard decision based on a pre-probability of the selected bit; and a reliability calculator calculating reliability of each of all the bits in the received signal based on the received signal from which the hard-decided bit component is cancelled and the estimated channel response. Accordingly, the computation amount according to detection can be reduced without the degradation of performance.

摘要： In one embodiment, a dimmer circuit is coupled to an electronic load and receives an alternating current (AC) signal. A phase control circuit turns the dimmer circuit on for a first portion of the AC signal to turn on the electronic load. The dimmer circuit turns off during a second portion of the AC signal to turn off the electronic load. A switch is coupled to the phase control circuit. The switch is controlled to couple the phase control circuit to ground when the dimmer circuit is off where the switch is part of a power supply supplying power to the electronic load.
