  • Apparatus for analyzing electrical signals of variable amplitude
    Patent number: 4103230
    Abstract: An electrical signal analyzing circuit for manually controlling the durational sequencing of an integrator circuit for providing visual readout of test signal divergence and maximum peak voltage levels. The integrator circuit is first time delay activatable for a predetermined duration according to a counter circuitry having a preselectable end of time count. The admittance of a variable amplitude test signal to the analyzing circuit is controllable according to a second time delay for a duration determined by the end of time count.
