    摘要： Techniques for suppressing large echo due to nonlinearity, instable adaptive filter, and so on. An echo cancellation system includes an echo canceller unit, a nonlinear echo detection unit, and a nonlinear echo suppression unit. The echo canceller unit (e.g., an adaptive filter) receives a reference signal and a near-end signal, derives an echo estimate signal based on the reference and near-end signals, cancels a portion of echo in the near-end signal based on the echo estimate signal, and provides an intermediate signal having residual echo. The nonlinear echo detection unit detects for large nonlinear echo in the echo estimate signal. The nonlinear echo suppression unit suppresses large nonlinear echo in the first intermediate signal based on a variable gain, which may be adjusted lower if large nonlinear echo is detected and higher otherwise.

    摘要： In various embodiments, a memory cell and a memory are provided. The memory cell comprises a Static Random Access Memory (SRAM) cell including a reset-set (RS) flip-flop and a Read Only Memory (ROM) cell being connected (or coupled) to the SRAM cell to set logic states of internal latch nodes of the RS flip-flop when the ROM cell is triggered. The size of the memory cells proposed in an embodiment of the invention is much smaller than the sum of the size of ROM cells and the size of SRAM cells with the capacity of the memory cells same as the sum of the capacity of the ROM cells and the capacity of the SRAM cells.

    摘要： Various embodiments of systems and methods for reducing audio noise are disclosed. One or more sound components such as noise and network tone can be detected based on power spectrum obtained from a time-domain signal. Results of such detection can be used to make decisions in determination of an adjustment spectrum that can be applied to the power spectrum. The adjusted spectrum can be transformed back into a time-domain signal that substantially removes undesirable noise(s) and/or accounts for known sound components such as the network tone.
