What is used to recover the signal, which is analogue of the flow rate

1.	What is used to recover the signal, which is analogue of the flow rate being measured?(a) Low-pass filter(b) Phase sensitive detector(c) Gating Circuit(d) Bandpass filterI got this question in my homework.The question is from Cyber Medicine topic in portion Telemedicine Technology of Biomedical Instrumentation
Answer» The correct answer is (b) Phase sensitive detector For explanation I would say: A phase sensitive detector is used to recover the SIGNAL, which is an ANALOGUE of the flow RATE being MEASURED. This type of demodulator not only offers maximum signal-to-noise ratio but also helps in the rejection of interfering voltages at frequencies well below the carrier frequency.
