fetal heart beat
&Sounds
probe.
Fetus heart  beat detector.
The ES-100VX Minidoppler is designed to receive blood flow velocity information through the use of ultrasound. A specific frequency is transmitted from the probe to the patient.
The transceiver amplifies a high frequency oscillation output for transmission to the transducer. The voltage is converted by piezo electric crystal  (transducer ) to ultrasound. The ultrasound beam is transmitted to blood cells flowing through arteries or to a beating fetal  heart .The ultrasound beam is reflected by the red blood cells or by moving structures and received by the crystal in the transducer, which converts the ultrasound into voltage. A doppler shift acurs between the emission and reception of the ultrasound beam.
The voltage is amplified. The electronics amplify the signal, filter out noise and improves the S/N ratio.The Doppler shifts signals are amplified  further and converted to audibe sound via the  integrated speaker.
