  • Patent number: 6526365
    Abstract: The invention is a method of measuring transfer functions of a physical system using a wideband excitation signal by exciting the system with a low-power, wide band input signal that has a rich frequency content over a wide band and using a stochastic process to derive a system transfer function over the excitation signal bandwidth.

  • Patent number: 6470285
    Abstract: A method and apparatus for rejecting signals exhibiting pulse pile-up and devices incorporating the method and/or apparatus. A pulse sensor senses pulses and an analog-to-digital converter digitizes the sensed pulses into discrete ADC values over a plurality of time slices. The digitized pulses are stored in a FIFO memory for processing by a classification processor. The processor qualifies the pulse and marks its first time slice. The processor includes accumulators that calculate parameters from various regions of the pulse. The calculated parameters are compared to criteria from identical regions of known, non-piled pulses. Pulses whose calculated parameters meet the criteria are accepted and stored in one memory location, and pulses whose calculated parameter do not meet the criteria are rejected and stored in another memory location.
