近几年来,根据很多高等院校开设“微弱信号检测”课程的需要,南京大学信息物理系受国家教委教学仪器研究所委托,研制了主要用于教学的JB-1型取样积分器。并于1987年5月通过省级鉴定。根据教学、实验的特点,JB-1型取样积分器的电路、结构都作了精心的设计。它可方便地利用机内伴有噪声的模拟信号(方波、三角波、正弦波)进行从噪声中检测信号波形的
In recent years, according to the needs of many colleges and universities to set up the “weak signal detection” course, Nanjing University Information Physics Department commissioned by the State Education Commission Teaching Instrument Institute, developed mainly for teaching JB-1 sampling integrator. And in May 1987 passed the provincial appraisal. According to the characteristics of teaching and experiment, the circuit and structure of JB-1 sample integrator have been carefully designed. It can easily use the machine with noise analog signals (square wave, triangle wave, sine wave) from the noise detection signal waveform
