doppler shift is also called |
doppler frequency |
|
|
The process of extracting the low doppler frequency from the transducer's carrier frequency is called ____________. |
demodulation |
|
|
doppler shift = |
reflected frequency - transmitted frequency |
|
|
The Doppler Equation: |
doppler shift = 2 x velocity of blood x transducer frequency x Cos() / prop. speed |
|
|
doppler shift is [inversely|directly] related to the velocity of the blood cells |
directly |
|
|
the x-axis of a doppler spectrum represents ______. The y-axis represents _________. |
time - doppler shift or velocity |
