A set-reset latch is a basic building block of computers and can be used to store state information. Here, by testing the influence of the two logical input signals on the reliable set-reset latch logic operation in the bistable system, we found that there are two types of input signals, namely, suprathreshold and subthreshold signals. For the suprathreshold signals, reliable set-reset logic operation can be achieved without any driving forces and exhibits certain anti-interference ability; for the subthreshold signals, a single harmonic could induce correct set-reset latch logic operation but with a narrow optimal parameter region. The introduction of biharmonic-induced set-reset latch logic operation (logical vibrational resonance) could greatly expand the parameter region. Explanations for the above results were provided by taking the logical inputs as the dynamic bias to analyze the dynamic changes in the system. Finally, the results were further verified by circuit simulation and actual hardware circuit.

在双阈值信号和亚阈值信号下，双稳态系统中的置位复位锁存逻辑操作。

置位重置锁存器是计算机的基本构建块，可用于存储状态信息。在这里，通过测试两个逻辑输入信号对双稳态系统中可靠的置位复位锁存逻辑操作的影响，我们发现输入信号有两种类型，即超阈值信号和亚阈值信号。对于超阈值信号，无需任何驱动力即可实现可靠的置位复位逻辑操作，并具有一定的抗干扰能力；对于亚阈值信号，单次谐波可以引起正确的置位复位锁存逻辑操作，但具有较窄的最佳参数区域。双谐波感应的置位复位锁存逻辑操作（逻辑振动共振）的引入可以大大扩展参数范围。通过将逻辑输入作为动态偏差来分析系统中的动态变化，提供了以上结果的解释。最后，通过电路仿真和实际硬件电路进一步验证了结果。
