An integrated circuit comprises a main bus, one or more integrated processors, an external bus interface, memory, internal bus controller, a signal analyzer, timers, reset/clock generator, radio controller, optional data converters, and optional radio. The signal analyzer performs both time-domain and frequency-domain analysis of the input signal and supplies data to the one or more integrated processors for signal classification.
