BIPOLAR WAITING MULTIVIBRATOR Russian patent published in 2000 - IPC

FIELD: pulse equipment, automatic control and regulation equipment, in particular, for pulse selection according their signs. SUBSTANCE: device generates pulses which have given amplitude and duration and which sign is equal to sign of starting pulse. Device has two electronic gates using transistors VT1 and VT2 with opposite conductance types, which are connected in parallel to feedback circuit using transistors Vt3 and VT4, and are fed by power supply with middle point terminal. Starting pulse enters common leg and opens either gate depending on sign. This results in positive or negative rectangular pulse with respect to middle point of power supply. Pulse amplitude is equal to positive or negative voltage of power supply with respect to its middle point. Duration of pulse depends on time-setting capacitor in feedback circuit. EFFECT: increased stability to noise, increased reliability of operations, when new starting pulse enters before end of generation. 6 dwg
