Step 103: judge whether the first parameter is greater than the first predetermined threshold value;
Step 104: when the first parameter is greater than the first predetermined threshold value, open the elimination interference function of the first elimination interference module.
In the present embodiment, step 101: obtaining a pending signal, please refer to Fig. 1 b, can be directly to obtain a digital signal, for example, be for example, by digital signal acquiring unit, the digital signal directly collecting for microphone 10.Further, can also, by modular converter 11 amplification that gains, then obtain this pending signal.
In another embodiment, please refer to Fig. 1 b, step 101 specifically comprises the following steps, in the process of electronic device works, signal gathering unit by electronic equipment, for example, collect an analog signal for microphone 10, and analog voice signal is through modular converter 11, carry out mould/number conversion and gain conversions and process, export a pending signal.
In addition, please refer to Fig. 1 b, in step 101, obtain a pending signal, because the residing environment of electronic equipment can not be desirable zero noise, after collecting unit 10 collects signal simultaneously, before the pending signal of modular converter 11 output, also can introduce interference signal, therefore pending signal comprises the first voice signal and the first interference signal, and the first interference signal can be noise, echo, thermal noise or its combination.
In step 102, based on pending signal, obtain the first parameter of pending signal.
In one embodiment, be specifically as follows: pending signal is processed by backup chip 120, obtains the pending backup signal of pending signal, and pending backup signal comprises the first voice signal and the first interference signal; Pending signal is processed by eliminating unit 121, eliminates the first interference signal, obtains the signal after an elimination is disturbed; Control chip 122 is based on pending backup signal and eliminate the signal after disturbing, and obtains the first parameter of pending signal.
