1·Sleep substances and most sleep centers are probably just modulators of sleep, only partly associated with any underlying benefits of sleep.
睡眠物质与大多数睡眠中心可能只是睡眠调节器，只是与睡眠的主要功效有关。
2·Engineers need to create ideal and worst-case signals to get accurate and accelerated insight into devices and designs such as semiconductor circuits, sensors or modulators.
工程师们需要创造理想的和最差的信号，以得到精确且具有深度洞察力的设备和设计，如：半导体电路、传感器和调节器。
3·Multi-order modulators shape the quantization noise even harder to higher frequencies.
多阶调节器在更高频率形成更大的量化噪声。
