A system and method for monitoring an analog data signal is provided that includes an analog data compression subsystem. The analog data compression subsystem includes a frequency bandpass filter, a rectifier, and an integrator such as a leaky integrator or one that is reset after being sampled. An analog data signal is bandpass filtered by the frequency bandpass filter, rectified, and integrated in the analog domain. The output of the integrator is converted into a digital data value by an analog-to-digital converter circuit that samples the integrator at a desired sample rate or duty cycle. The output of the integrator can trigger an event based upon established criteria. Multiple analog data compression subsystems can be used in parallel to monitor multiple frequency bands-of-interest.
