成果介绍

本发明公开了一种超声波胎心监测仪及其回波信号的数字解调方法，数字解调方法包括A、主控模块输出控制指令控制CPLD模块输出激励脉冲信号；B、信号放大模块将激励脉冲信号放大、并经阻抗变换电路处理后、传输至超声探头进行激励；超声回波经过超声探头接收并转换成回波信号；C、所述回波信号经模数转换模块进行模数转换后生成数字的回波信号，传输至CPLD模块进行数字解调生成I信号和Q信号并反馈给主控模块；D、主控模块接收到I信号和Q信号后再次输出控制指令给CPLD模块，并将I信号和Q信号传输至显示屏显示；能获取更真实的I/Q信号和频移信号包络，解决了心率翻倍的问题；还能对特定的深度进行组织运动的监测。
