Question 48
INMCQ2 marksNeeds review
Consider an ultrasonic measurement system shown in the figure. The ultrasonic transmitter (T) sends a continuous wave signal
volts towards an object whose vibration is modeled as
volts. Neglecting the phase shift due to any other effect, the received signal at the receiver (R) is
volts.Assuming the frequency sensitivity factor as 500 Hz/volt,
kHz,
kHz, the modulation index (
) and the frequency deviation in
, respectively, are
