Spectrum Doppler Processor Board, SDP
5-11-9-1
General Description
•
This board performs Spectrum Analysis on the Doppler signals and makes the velocity traces,
•
The Doppler audio channels are generated on this board.
•
During Duplex modes (e.g. 2D and Doppler), The Missing Signal Estimator will fill the gaps in the
Doppler spectrum by stretching the "real" spectrum out to fill the missing time.
•
A serial link from the Internal I/O board, feeds the A/D converted traces (like ECG, Phono and
Pressure) into the SDP. These signals are sent together with the Doppler data via the Pipelink bus
to the Image Port Board.
