摘要：
System of the present invention carries out lie detection system using E.E.G in relation to a kind of,It is that input unit collects E.E.G signal using brain wave electrode patch,E.E.G signal is sent to E.E.G signal processor,Signal is amplified,Frequency needed for eliminating noise and capturing,E.E.G signal is converted into digital date by analog signal via arithmetic system is detected a lie again,And store digital date and carry out operation of detecting a lie,Operation of detecting a lie adds up the digital date of different stimulated object signal out of the ordinary,And the digital date of different stimulated object signal compared by most Hou,Use do not Chu testee say it is whether true and false,Reach the function of detecting a lie. Stimulant signal is switched to such as image, text or sound to collect testee's E.E.G by output equipment, and when the stimulant signal of presentation is relevant with testee, the E.E.G generated at this time then can nothing to do with connection stimulant signal difference.本發明係有關一種使用腦波進行測謊系統，利用腦波電極貼片為輸入單元收集腦波訊號，將腦波訊號傳送至腦波訊號處理器，將訊號放大、消除雜訊及擷取所需之頻率，再經由測謊運算系統將腦波訊號由類比訊號轉換成數位資料，並儲存數位資料及進行測謊運算，測謊運算將各別不同刺激物訊號之數位資料累加，及最後比較不同刺激物訊號之數位資料，藉以辦別出受測者所言是否真假，達到測謊之功能。輸出設備將刺激物訊號轉為如影像、文字或聲音等以收集受測者腦波，當呈現的刺激物訊號與受測者有關聯，此時產生的腦波則會與無關聯刺激物訊號不同。
