Non-directional Doppler/ Non Coherent/ Hand held Doppler - ANSWER-a basic doppler system that simply measures movement, by the presence of a frequency shift (can ONLY detect that) Bi-directional Doppler - ANSWER-uses phase quadrature to distinguish flow direction with a special set of headphones Phase quadrature - ANSWER-separates the echo frequencies to positive and negative shifts and send that data to separate headphones Continuous Wave - ANSWER-always two crystals Continuous Wave...

Physics Doppler quiz questions and answers 2024 solved What information does the Doppler shift furnish concerning the blood cells that produce it? - Ans - velocity The frequency of a pulsed Doppler wave is 6 MHz, and the PRF is 5 kHz. What is the maximum Doppler shift that can be recorded without aliasing? - Ans - 2.5 kHz When a reflector moves toward the transducer, what will happen to the reflected frequency? - Ans - increase Which of the following is not include in the information...
