  • Device for indicating pole-zero cancellation, in particular for amplifiers for ionizing radiation spectroscopy
    Patent number: 4491799
    Abstract: The device consists essentially of a sampler device for sampling the baseline after every pulse processed in the spectroscopy amplifier, coupled to an averager circuit for averaging the samples, and to a LED display device, coupled to the average output and giving a visual indication of the value and sign of the averager output signal, the sampler and average circuits forming a so-called "boxcar integrator", that is an essentially RC low-pass filter having a switch in series to the resistor.
