摘要
脉搏测量是检测有无的测量,使用的传感器是红外接收二极管和红外发射二极管。信号经过放大后,窄脉冲代表有脉搏,低电平代表无脉搏。为了克服干扰,设计了低通放大器。
The pulse measurement is to detects pulses and pulseless. The narrow impulse represents pulse, andlow voltage represents pulseless. The sensor is infrared receiving diode and infrared emission diode. Low-pass filterwas designed in the amplifier for conquering disturbs.
