Time-Frequency Logic For Signal Processing

:

In this talk he will first introduce Time-Frequency Logic (TFL), a new specication formalism for real-valued signals that combines temporal logic properties in the time domain with frequency-domain properties. He will then present a property checking framework for this formalism and demonstrate its ex- pressive power to the recognition of musical pieces. Like hybrid automata and their analysis techniques, the TFL formalism is a contribution to a unied systems theory for hybrid systems.
This is joint work with Alexandre Donze, Oded Maler, Dejan Nickovic, Ezio Bartocci and Scott Smolka.
