摘要： An asymmetric modulation scheme may be used to drive two output nodes coupled to a load. The asymmetric modulation scheme may be one-sided such that the switching rate of a first output node is lower than the switching rate of a second output node. The first output node may be switched only to change a direction of current between the first output node and the second output node, while the second output node is switched to convey the information of an input signal. The asymmetric modulation scheme may be used to drive a speaker to reduce noise at the first output node to improve accuracy of current monitoring through the speaker by a current monitor coupled at the first output node.

摘要： Methods, apparatus, and systems to determine a niche market of items or services, the first phase of which identifies a gap between demand and supply for a set of items. Session logs may be evaluated to compare transactions involving a specific item to those of a larger group of items. The resultant information identifies areas of high demand, but with low availability. The niche market information may be provided as direct merchandising items for sellers. In one example, the method generates niche market item web pages in specific categories. Additional methods, apparatus, and systems are disclosed.

摘要翻译：可以使用非对称调制方案来驱动耦合到负载的两个输出节点。非对称调制方案可以是单向的，使得第一输出节点的切换速率低于第二输出节点的切换速率。第一输出节点可以仅被切换以改变第一输出节点和第二输出节点之间的电流方向，而第二输出节点被切换以传送输入信号的信息。可以使用非对称调制方案来驱动扬声器以减少第一输出节点处的噪声，以通过耦合在第一输出节点处的电流监视器来提高通过扬声器的电流监视的精度。
