1.	Ultrasound provides basically clearer signal than does phonocardiography.(a) True(b) FalseI have been asked this question in homework.My doubt is from Recording System topic in section Foetal Monitoring Instruments of Biomedical Instrumentation
Answer» The CORRECT option is (b) False The explanation is: False, PHONOCARDIOGRAPHY provides a basically cleaner signal than does ultrasound, thus allowing a greater chance of detecting a smooth BASELINE FHR. Unfortunately, phonocardiography is more susceptible to artefacts introduced from ambient noise, PATIENT movement or other intra-abdominal sounds.
