Problems solved by technology

[0003] Mobile terminals, because of their portability, are more popular among people, but at the same time, there is a problem that the battery life of mobile terminals is relatively limited.
This type of audio and video files consumes a lot of power at high frequencies, and generally their power at high frequencies is several times higher than at low frequencies, which will lead to a substantial increase in power consumption of mobile terminals and lead to The battery life is greatly reduced

Embodiment 1

[0041] see figure 1 , a method of attenuating the power of a signal according to its frequency, comprising:

[0042] S101. Obtain the relationship between the frequency of the signal and the current.

[0043] In step S101, the current of the signal is easier to sample than the frequency of the signal, and the current value of the signal is used to analyze and characterize the frequency of the signal, so the relationship between the frequency of the signal and the current must be obtained.

[0044] S102. Sampling the current of the signal, and determining a frequency monitoring point of the signal according to the relationship between the frequency of the signal and the current.

[0045] In step S102, the current values ​​of several signals are sampled, and according to the relationship between the frequency and current of the signals described in step S101, the current values ​​of several signals correspond to the frequency values ​​of several signals, and the frequency value...

Embodiment 2

[0051] see figure 2 , a method of attenuating the power of a signal according to its frequency, comprising:

[0052] S201. Under the rated voltage, obtain the relationship between the frequency and power of the signal.

[0053] S202. Acquire the relationship between the frequency of the signal and the current according to P=UI and the relationship between the frequency and power of the signal.

[0054] Step S201 and step S202 are methods for obtaining the relationship between the frequency of the signal and the current.

[0055] For example: by step S201, the relationship between the frequency and power of the signal obtained at a certain rated voltage is P=Y(F), where F represents the frequency of the signal, P represents the power of the signal, and Y represents a certain functional relationship, Y can be be a continuous function or a discrete function.

[0056] Depend on P = Y ...

Embodiment 3

[0083] see image 3 , a device for attenuating the power of a signal according to its frequency, comprising:

[0084] The frequency-current relationship acquisition unit 10 is configured to acquire the frequency-current relationship of the signal.

[0085] The frequency monitoring point determination unit 20 is configured to sample the current of the signal, and determine the frequency monitoring point of the signal according to the relationship between the frequency of the signal and the current.

[0086] The power attenuation unit 30 is configured to attenuate the power of the signal with a preset attenuation coefficient at the frequency monitoring point of the signal.

[0087] The device of the present invention determines the frequency monitoring point of the signal according to the current of the signal, and attenuates the power of the signal with a preset attenuation coefficient at the frequency monitoring point of the signal; especially the present invention can solve ...

Abstract

The invention relates to the technical field of power control, in particular to a method and device for attenuating power of a signal according to frequency of the signal. The method comprises the following steps of obtaining the relation between the frequency of the signal and current; sampling the current of the signal, and determining a frequency monitoring point of the signal according to the relation between the frequency of the signal and the current; attenuating the power of the signal at the frequency monitoring point of the signal according to a preset attenuating coefficient. According to the method, the frequency monitoring point of the signal is determined according to the current of the signal, and the power of the signal is attenuated at the frequency monitoring point of the signal according to the preset attenuating coefficient. By means of the method, the power of the signal can be attenuated according to the preset attenuating coefficient when the signal is at the high frequency and has high power, so that the power consumption of the device is effectively controlled, and the cruising capacity of the device is improved.

Description

technical field [0001] The invention relates to the technical field of power control, in particular to a method and device for attenuating the power of a signal according to its frequency. Background technique [0002] With the reduction of terminal hardware costs and the diversification of the software market, terminals have entered every aspect of people's lives. It can be seen everywhere that people use terminals for office, study, entertainment, etc. Terminals have become a very important part of people's lives. important composition. [0003] The mobile terminal is more favored by people because of its portability, but at the same time, there is a problem that the battery life of the mobile terminal is relatively limited. [0004] In particular, there are some audio and video files such as fighting games in the current software market. The signal frequency of such audio and video files is usually relatively high, and the reference range of the signal frequency is 5KHz-...
