- Because of the effects of the wind-noise, sound-noise, strong electromagnetic interfere, sensor itself, and the magnified circuit etc. at the survey spot, the received transducer signals often include noise signals of multi-frequency disturbance. Under serious circumstances, such noise signals would submerge the input signal need-extracted, therefore resulting the system cannot obtain the surveyed signals. Filter measures should be adopted, noise should be exterminated by signal filter, so that to enhance SNR of the system. When high-speed dropping parachutist issue orders, when recording at noise meeting spot, or other such complex surroundings, filter of such functions is needed, it can also be applied in area of message technology treatment of military and civil use.
