Surface electromyography (SEMG) is a one-dimensional time series of voltage signals which are induced, amplified, displayed and recorded by the surface electrodes during the spontaneous and non-spontaneous activities of the neuromuscular system, its amplitude is about 0-5000 V, frequency 0-1000 hz, signal form has strong randomness and instability. Compared with the traditional needle electromyography, the spatial resolution of SEMG is relatively low, but the detection space is large and the repeatability is good, it has important academic value and application significance for sports science research, rehabilitation medicine clinical and basic research and so on. Filter circuit module, Surface EMG signal generally only millivolt level voltage, signal often with low-frequency and high-frequency interference signal, the real useful EMG signal between 10Hz-500Hz. In addition, the 50Hz power frequency signal is also an important interference source, if not removed may cover the surface emg signal, according to these special requirements, the special filter must have the isolation, filtering function, it also requires high Common-mode rejection and good anti interference. The low-pass filter uses voltage controlled voltage source type second order low-pass filter. 50Hz power frequency signal has a great influence on surface EMG signal acquisition, its frequency is just in the frequency band of surface emg energy concentration, and its amplitude is 1-3 orders of magnitude larger than surface emg signal, so it must be removed. In this design, double t Active filter are used to filter the 50Hz power frequency signal. The following analysis may introduce the power frequency interference: 1 by the space radiation: The space electromagnetic field may be induced by the current of the corresponding frequency component through the electrode connection in the detection equipment, the connection on the printed circuit board, the device pin or the device itself, into noise mixed with EMG signals. Electromagnetic fields in space can come from a variety of sources, most fatally from power-line interference caused by grid radiation. The DC power supply is introduced by DC POWER SUPPLY: in the testing equipment, the DC power supply for active devices is usually obtained by power frequency AC power supply voltage transformation, rectification, voltage stabilization. The ideal filtering effect can not be achieved by DC power supply. The power frequency (or its harmonic) current in the form of a ripple is introduced into the amplifier through the power supply. 3 introduced by the subject's body: the subject's body exposed to the electromagnetic field in space will also be induced by the electromagnetic field, the subject's body will be induced by the power frequency current through the detection electrode, it is added to the input of the amplifier together with the bioelectric signal to form the power frequency interference. Aiming at the power frequency interference of DC power supply, the battery is used to power the active device. The use of battery power supply not only avoids the power frequency interference caused by the ripple of rectifier power supply, but also eliminates the possibility of electric shock to the subject due to leakage. Because the voltage of the battery is low and the volume of the battery is large, the DC / DC module is used to boost the power supply of the chip.
