A remark on incoherent feedforward circuits as change detectors and feedback controllers
This note analyzes incoherent feedforward loops in signal processing and
control. It studies the response properties of IFFL's to exponentially growing
inputs, both for a standard version of the IFFL and for a variation in which
the output variable has a positive self-feedback term. It also considers a
negative feedback configuration, using such a device as a controller. It
uncovers a somewhat surprising phenomenon in which stabilization is only
possible in disconnected regions of parameter space, as the controlled system's
growth rate is varied
