Abstract

A mobile terminal and a clutter signal suppressing circuit thereof are disclosed. The clutter signal suppressing circuit comprises: a narrow-band bandpass filter (20) disposed between a clock signal generator (1) and a function module (10). The mobile terminal comprises said clutter signal suppressing circuit. The technical solution allows a clock frequency signal to pass normally and efficiently, and all clutter signals such as harmonic waves and strays except the frequency are suppressed, therefore the electromagnetic interference of the clock clutter on the device is reduced.

The part of the novel that is described in the Ming Dynasty is a part of the present invention, and the schematic of the present invention is not limited to the present invention. In the middle force phase of the wood, the 2nd phase of the wood is filtered in the form of a filter. The 0 3 force phase is filtered in the form of a filter. The 4 force phase of the wood is filtered in a high-filter form. Wave 6 of the new type of terminal-inhibited 5 7 of the novel form 8 of the novel form 9 of the novel form of the suppressor. In the way, the new type will not be described in the reference. What needs to be clarified is that in the case of no, the special ones in this book are mutually exclusive. 6 The new type of narrowband filter 20 for the termination of the terminal is in the same state as the energy source. The phase filter and the high filter can only be filtered out or cannot be resolved. However, since the filter is suppressed, the high sum is filtered out only by the frequency, and the frequency is often suppressed, and all the waves other than the frequency are suppressed and reduced. In the suppression path described above, the filter package container and the sensor are in the same state. 7 The new form of the generator 3 4 0 can. The ratio of C of the container of the sensor in the suppression path is greater than 200. The ratio of C, which is ultimately required to suppress the container and the sensory sensor, is greater than 2 / in order to achieve the desired suppression. In the suppression path described above, the filter package container and the sensor are grounded in the same way. 8 The new form of the live processor 3 4 0 hand can. The ratio of the C sensor of the container in the suppression path is greater than 2 / . The ratio of the C sensor that is ultimately required to suppress the container of the container and the sensor is greater than 2 / to achieve the desired suppression. The proposed way of suppressing God is. There are forms that each contain a mediation. Among them, the divine power will be in the direct walking, and the other divine power will be in the same place. The form of the gods is filtered. Due to the following characteristics, the frequency impedance is the smallest and the impedance of the frequency is the largest. The filter with the highest frequency impedance and the lowest impedance of the frequency is suppressed by the filter of the desired frequency of the desired frequency. In the suppression path of the item, the terminal is a handwriting. In the suppression path of the item, at least the radio, the picture, the picture, and the picture can be included. The suppression path is used to suppress the outside of the system, the image, and the W in the handwriting. 9 The suppression of the new form of the living device. Among the filtering of the remaining components, the filtering frequency within the filtering frequency is high and the loss is suppressed to a large extent.

It is also necessary to consider the cost of the hand-painted layout. The same requirements are required for the device, so only the filter can be used. The existence of the filter is that the filter is filtered by some frequency and the intensity of the wave is the highest. The way in which the phase is used is negligible or unsuppressed. What is the characteristic of the rabbit's characteristic drop? The wave is especially dependent on the frequency required in the bandwidth and its signal suppression. The proposed new type

The high frequency of the frequency other than the frequency has a certain degree of inhibition. In particular, the frequency of the wave is only suppressed by d.

The rate is basically controlled below -4 d.

And the new form of the external suppression is high. In particular, the secondary strength of filtration is greatly increased. It is worth noting that the description of this new type mentions 7 forms and 8 forms. The filter of this new type is not determined in the way of other. This is the new way of rest. The new method of suppressing the hand wave is much lower than the original method and the high frequency has a stronger characteristic filter, which greatly reduces the internal reference of the handwriting. Especially in the current situation of smart users, the multi-angle and multi-angle measures are not very effective. The termination of the terminal suppresses the filtering of the frequency of the channel formed by the channel, and all the waves other than the frequency are suppressed and reduced. In view of the new type, the new type of wood used in this field is not used in this field. Any repairs, equivalent substitutions, etc. made within the spirit and principles of this new type are included in the warranty of this new type.
