In the present embodiment, due to a human body inherently high resistant, the amplifier that acquisition receives brain wave is necessary
It is high input impedance amplifier.Since difference amplifier is the prime of micro voltage amplifier, to common mode inhibition when ginsengs such as temperature drift
Several requirements is very strict.
As shown in figure 5, this grade of amplifier using the OP-07 of U.S.'s production as main amplification chip, to reduce its amplifier in itself
Noise signal, and Rf1/R1 is required strictly equal must just to prevent scurrying into for common-mode signal with Rf2/R2.Consider that each resistance has
Certain error, therefore the method for using fine tuning Rf2 is realized.

It is added between input terminal and ground, excessively high common-mode voltage can not only influence measurement accuracy, but also may burn out instrumentation amplifier.With
Photoelectric coupling or transformer coupled transmission signal.Isolated amplifier has following distinguishing feature：
1. protection data collecting system makes it not damaged by high common-mode voltage.
2. since the importation of isolated amplifier is completely floating, biasing resistance is provided without to input terminal, thus
There is no bias current lead, Leakage Current very little solves the problems, such as noise pickup.
3. since input is broken to public disconnected capacitance and leakage conductance very little, there is very high common mode inhibition capacity, it can be right
Direct current and low frequency signal carry out the measurement of entirely accurate.
Bandpass filter（BPF）, in actual design, always wish that BPF has good selectivity, the gain in passband
High and energy steady operation.But when high gain, the stability and reliability decrease of BPF.Phenomenon one is：BPF is easy certainly
Swash；The second is passband gain is unstable.Working as variation of ambient temperature, the resistance R, capacitance C values in bandpass filter are changing,
Influence centre frequency.
General capacitance has negative temperature coefficient, and resistance has positive temperature coefficient, but is difficult to realize and exactly matches.Make high-order
The experience of BPF is：Passband gain should not be too big；The first order makees differential amplification using instrumentation amplifier, and to the first cascade screen；
The layout of entire amplifier is ' one ' font layout；Using one point earth.

Multiple interactive object to be shown.
For example, applying for typewriter mode in example is based primarily upon by EEG signals is realized to the typewriting of the auxiliary of user, because
The mood of people on typing position is more stable, so not needing to consider to judge the current mood shape of user
The heart rate signal of state and the oxygen saturation signal for judging the current physical condition condition of user.Standard is not only realized in this way
The purpose of true auxiliary user's typewriting, it would also be desirable to which the data volume of processing falls below minimum.
For example, EEG signals and heart rate signal can be considered for the embodiment of expression pack mode to realize that auxiliary is used
Family selects facial expression image.For example, determine that user is in the stable state of mood and still compares by the heart rate signal of user first
The state of excitement, if more stable state just preferentially shows more stable facial expression image under display interface（For example,
Smile expression）, if more exciting state just preferentially shows more exciting expression under display interface（It is for example, wild with joy
Expression, violent rage expression etc.）, in order to be used for that the expression and the selection that meet oneself current state of mind to be found with most fast speed.
For example, EEG signals and oxygen saturation signal can be considered for the embodiment of game mode to assist using
More reasonably play game in family.For example, the current physical condition and think of of user is determined by the blood oxygen saturation of user first
The agility state of dimension（Generally, the better thinking of the higher physical condition for showing people of blood oxygen saturation is also quicker）.When judgement is used
The bigger game of user some difficulty then can be preferentially shown to when the blood oxygen saturation at family is higher, to provide to the user more
Challenging game allows user preferably to be experienced.It then can be more preferential when the blood oxygen saturation for judging user is higher
Some difficulty of user are shown to than relatively low game, to provide the game more mitigated to the user.So as to all present always
The game of user's current physical condition is most suitable for user.
