FIELD: physics. ^ SUBSTANCE: pseudocoherent detector contains reference generator, two balanced synchronous amplitude detectors, two low-pass filters, phase shifter to pi/2, adder, storage device, two voltage module control devices (MCD), interconnected in specified way. Each voltage module control device contains two diodes, adder and inverter. The inverter is c connected consequently before one diode. After quadrature signals are extracted, they are made to pass through MCD. MCD provides to extract quadrature modules. Resulting voltage is calculated by addition of voltage modules from outputs of balanced amplitude detectors. ^ EFFECT: simplification of video pulse shaping and elimination of hard-driving amplitude modulation of peak video pulse values. ^ 5 dwg |
