Doppler sub-boards add the signal-processing chain that extracts velocity information from returning echoes: quadrature demodulation, wall filtering, spectral analysis, and (for color flow) autocorrelation. PW Doppler typically shares the front-end; CW Doppler often uses a dedicated pair of elements on the probe and a dedicated analog demodulation board. Replacement Doppler boards are matched by host-platform revision and probe family.
