- We have implemented real-time switching between blend filters for ITMX. The switching relies on two identical filter banks for each DOF, the CURR and NEXT bank, each of which contains all the possible blend filters. We use a C code block in Simulink to turn on/off filter modules in the two banks and smoothly ramp from the output of one bank to another. A Perl script interfaces with MEDM and triggers the C code.
