COMPARATOR Russian patent published in 1998 - IPC

FIELD: pulse equipment, signal processing equipment, circuits testing tolerances. SUBSTANCE: proposed comparator includes voltage source presenting generator of alternating signal connected to first input of matching circuit which second input is input of comparator connected with its output to comparison element to which inputs both analyzed and alternating signals are fed whose swing is constant and frequency is higher than frequency of change of analyzed signal . Swing of alternating signal exceeds value of hysteresis of comparison element. EFFECT: formation of two-threshold characteristics with use of one single-threshold comparator with any hysteresis. 8 dwg
