摘要
利用数字信号合成原理开发的多功能音频信号发生器,可以产生正弦波、扫频正弦波、扫幅正弦波、正弦波猝发音、白噪声、粉红噪声和窄带白噪声等多种信号,可对外接信号进行程控放大,OCT滤波等处理;并带有10W功放输出。经测试,各项指标达到了JJG607—2003中规定的技术要求。
Through the multi-function audio signal generator using the principle of digital signal composition,different signals including sine wave,frequency sweep sine wave,amplitude sweep sine wave,sine wave tone burst,white noise,pink noise and narrow band white noise etc can be generated.The external signal can be program controlled amplified,OCT filtered with a 10 W amplifier output.Through testing,all the indicators can meet the technical requirements of the JJG 607—2003.
